I started making this lip last Wednesday, it took +/- 22 hours to make, I already finished the lip and thought I would share to you the steps it took to make this real.

Materials:
~2" Foam board, used for insulating concrete, 4x8 sheets - Homedepot-$20
~Sandpaper, drywall (works well on the foam) 80, 120, 500, 1000, 1500 grit, - home depot - $20
~Fiberglass cloth material, 4 little bags 36"x36" - hoe depot - $30
~Carbon Fiber cloth material 3 cu yes, Composites USA - $145
~404 Epoxy Resin - Composites USA - $30
~404 Clear Gel Resin - Composites USA - $30
~404 Epoxy Hardener 3:1 Ratio - Composites USA - $20
~Paintbrushes 1" & 2" - qt 20 - home depot - $20
~plastic spatulas for pushing air bubbles out - Home depot - $10
~20+ hours of intense work on this - DIY GARAGE IN MY HOME - PRICELESS!

So that’s the list of materials, now let’s get down to the actual lip. After deciding on what type of lip you are going to make, I chose something way to advanced for carbon fiber, especially since this is my first project involving these materials. This is what I planned on, yet it turned out to be very basic and looks awesome in the end.

The lip I wanted to make:
http://www.nfcperformance.com/images/Lip-Kits-Lexus-Mugen-FRONT.jpg

After approximately 30 mines of mooch up using masking tape and cardboard, to place a general picture of what I wanted on the car, I decided this would be very hard to replicate on CF material. So we cut back on the open vent area in the bumper and went with a low profile Sit Limited type CF lip.

After making a direct copy of my bumper on Cardboard, I traced the pattern onto the foam board and started cutting and sanding; this was a short but important step that gave ship to the lip.

This is where the fun starts get your respirator out and lots of gloves! First clean off a nice area and mat it down with cardboard or plastic on the floor, resin sticks to everything especially clothing, my brother was wondering what the white mystery stains on my pants were the following morning, loll.
I don’t have pictures of the actual process involving me placing the cloth on the foam and painting it with resin. So ill describe it to you as best I can. First clean off the foam board using a wet towel be sure to make sure to let the foam dry off before applying any cloth and resin, also it doesn’t matter if you cover the entire foam with fiberglass this specific foam is water resistant and can take the abuse, although after a few years of winter and rain it may start to deteriorate, so be sure to close it up well.

Now for the application of fiberglass, Be SURE TO PRE-CUT the cloth prior to pasting it on the foam, this is so you don’t touch resin on the clean cloth making it sticky and already having a possibility of drying out on the cloth. So precut always. After cutting the cloth into pieces about 3”x 8” make a pile near your work area easily accessible from the lip so you can do piece after piece before letting it dry. The Resin has about 15 mines of play time before it gets sticky and will be hard to work with so be sure to work fairly quickly.

Have several plastic or hard paper cups available at all times, fill about 5 of them up with Resin only about 3-4 tablespoons worth. DON’T ADD the hardener until you decide to apply the epoxy within the next minute, it will start drying and be impossible to work with. After you have the cups filled with epoxy and hardener to the first cup, I used 3:1 ration hardener so for every three tablespoons of epoxy one tablespoon of hardener. After mixing the two, be sure to stir it up good to make the glue well mixed for application, you don’t want to wake up next morning with the resin still drying. Now as far as the application goes, applying enough epoxy/hardener mix to the foam board to cover the area you have cut out in fabric, as soon as you apply glue to the foam apply the cloth onto. Now work it onto the foam and be sure to have no bubbles or white spots visible the whole piece of cloth should be damp with glue, but don’t overdue it so it causes drips of glue, this will look like ilovemenilovemenilovemen in the end and will be sanded down anyways. After completing the first piece of cloth work to the sides and be sure to cover the whole foam board lip, or everything you wish to be made of fiberglass. After applying the cloth over the entire surface, let it dry 5-9 hours for my particular epoxy mixture. After letting it dry and its hard, sand it down enough to leave scratches in the glassing, I used 80 grit anti-clog papers. After you sand, apply another layer just like the last, start in the middle and work out to the sides. Repeat this process until you’ve built up a few layers, I went to 6 layers of Fiberglass.

Hers what is looked like after the glassing?

Now that you have the basic shape mocked up you are ready to start using bond! This stuff is great! Start off by sanding the fiberglass a little just scratching the surface making rough for the bond to stick, now I applied bond to the entire lip, just before doing this I trimmed all the excess fiberglass cloth and overhang material off using a rot zip and Hacksaw. Applying the bond press it hard on the fiberglass to fill all the scratches and holes, now after covering the entire thing, let it dry ~30 mines or so…I managed to poop and cook lunch between the drying of the bond. Now that its dry whip out sour 80 grit paper and go to the bondo making a somewhat smooth layer on top of the fiberglass, Do this to the spots that need leveling, Make sure you have no hills or holes on the fiberglass. THEY will stick out! After completing the 80 grit work onto 250 gritt. By now the entire lip should be smooth and ready for the next layer. Don’t go onto the next step until all the holes, cracks and hills are gone!

During Bondo Stage:

http://i109.photobucket.com/albums/n76/robsimprza00/IMG_0550.jpg

Now that we are completed with the bondo, put a layer or two of Black Primer on the top layer, this points out the little cracks and holes really well. Be sure to use easy sand primer spray. Fill the holes and sand away…

Now that we are done with primer, let it dry. Follow this up with some lube, lube the top layer really well with Vaseline, and make sure to cover the whole thing. Or you can use several applications of wax, something thick though. I used Carbons Turtle was with about 5 layers of wax on top of the primer. This will help later on when you separate the carbon fiber mold from the fiberglass. Or in your case if you want one piece and are not going to make duplicates, don’t apply wax or lube or anything!

Dark picture, after primer:
http://i109.photobucket.com/albums/n76/robsimprza00/IMG_0554.jpg

Now that everything is complete, cut a large sheet of Carbon fiber material; make sure it’s big enough to cover the whole lip without stretching to far! If you stretch the material it will also look like ilovemenilovemenilovemen!

After you spread the cloth around the lip, pull it tightly to the lip, I used masking tape to hold it on temporarily followed by electrical tape after the glue. You want to be sure the carbon fiber cloth is really tight against the lip to ensure bubbles and holes don’t form. This is why I used electrical tape, it doesn’t stretch easily. Now use the 404 Clear gel epoxy and mix that with hardener, again I used 3:1 ration glue so in your case it may be different, Now that you have the CF material taped down apply a good amount of glue mixture to the CF material, make sure to cover the whole thing and be sure you have enough glue to make the CF Dense with glue! Then squeegee out the excess and be sure there are no Drips or blobs or holes visible. Let it dry and Repeat the process with the CF material until you reached the desired amounts of layers.

Now its time for some clear coat, I used 1 full spray can which was about 6 layers worth of layers all to equal about 2mm thick. After the layers of clear coat dry, its time for wet sanding, this involves 1500 gritt wet sanding paper and a bucket full of water/soap mix. Be sure to only the parts that are wet with soap and water don’t touch the dry clear coat, or you will have scratches imbedded into the lower clear coat layers. Which may touch the CF material, and you won’t be happy.

After sanding about 3 hours the texture of the fabric should be unnoticeable and very smooth to the touch. Make sure the entire lip is like this, and final step is to the place a few layers of wax onto it. Afterwards you are completed with the project and ready to mount!

After the CF materials and Clear coat, Also final mounting:

If you've got a question i may have an answer, also if you would like me to make you one, I am not selling them yet. Just started out and am going to make some more stuff for some friends, Rear spoiler, Interior peices (for my car), Rear bumper spoiler and some other things i have gotten calls about.'

Thanks,

Like you said on NASIOC, quit your job and make these!~ok~ (Consider this another I want one post.)

Robk0000
06-21-2007, 08:41 PM
lol, idk its costing me ~$100 but i would sell it for like $350...but i would need to make a mold of your car, so that would take like 2-3 hours then i would have it done in like 1 week. plus you would get the design you want,

Nice job on the lip man. I was following along on the nasioc thread. Turned out real nice. Looking forward to seeing it in person somewhere along the line.

I checked into having someone make a spoiler for me already. Nobody wants to do it.

If you are willing that would be awesome. It seems you know what you are doing.

what are you looking to do? Simple small wing or something like an Sti wing?
I failed with the dash, its nearly impossible on one sheet of CF matting so i think im going to start on myfriends wing then see if someone would want something done too.

06-22-2007, 07:31 PM
Looks awesome man. I should have done this instead of buying one because I have done work with fiberglass before.

FoxGT
06-26-2007, 12:21 PM
i plan on doing this this summer.

seeing as I too have a custom fiberglass lip (that I didnt make), Id like to start doing this as well, possibly for the NE legacy crowd.


ive worked with fiberglass before so thats no the problem.


One question though... is the foam/fiberglass piece still inside the carbon fiber piece or did you simply use that piece as a mold? If you can use it as a mold u just answered a ton of my questions that I had when I was considering doing this.

Piece looks great and I congratulate you!

Robk0000
06-27-2007, 06:40 PM
the mold is still inside of the matting of CF, enclosed i should say. Im actually going to make another one soon, i just havent found the time, Looking for Ideas though, i will most likely make them from CF just because i have the material and am sure others would appreciate having the cf over fiberglass. If anyone has a suggestion on design plan i would try to accomadate that into my plans.

Thanks,
Rob K.

Robk0000
06-30-2007, 10:32 PM
Mold has been fiberglassed, now waiting for it to dry

:) looking real good right now, just got to sand and it will be ready for making a few outa CF!

Robk0000
07-01-2007, 05:01 PM
Front mold somehow ended up being glued to the floor...not good. i tried prying it off but it broke!

So now im making a rear diffuser for the rear bumper. mold already made and CF was already layed ontop, be dried out later tonight, thats only the left side though, i havent started the right portion.

going for round 2.


Im going for a different design this time, i got the mold this time from installing the ghetto garage door gasket on the front. It actually looks good, until you see the side. oh well.

So from here, now that i have the perfect curve of the bumper and exact size/shape i want. I can put a layer of glass right ontop of it. let it harden, and bam. New mold for the front bumper.

i will take pics whjen i get he first layer on.

I still get 2-3 emails a week of people wanting a custom lip or random cf shapes and stuff. I can make flat sheets easily, they just take a while.

the one i made for the L?

almost nothing its really light.

05-28-2009, 07:56 PM
how long to make a lip for me? :D

Robk0000
05-28-2009, 07:59 PM
it took me about 20 hours to make mine, between the carving of the foam forming and bondoing having a perfect mold to work with. Then all the layering of cloth. I believe it used 2 sq yds of .7mm CF cloth and 6 layers of fiberglass.

It takes along time, but the end result was awesome. Which is why is still hang onto it.

I wouldnt mind making another one, but you would have to give me your front bumper for about a week just to make a good design and mock it up for you.

Piece looks real awesome! Have you ever made any trunk spoilers similar to this??


http://www.blacktopaero.com/shop/catalog/images/P1010221.jpg

I want one for my 08, but no one makes them yet....

Robk0000
05-29-2009, 05:24 PM
looks pretty straight forward, i mean getting teh first shape to look like that would be a bit hard, but its doable.

id do it, get me a wrecked 08 trunk lid and i will make one for a demo. :)
