Thread: Working to make body parts 1 piece/molding

I am very unfamiliar with auto body work, but I plan on taking a venture into making an interesting hood in the next couple of weeks.

My hood is Carbon Fiber.

The only things I've heard of is bondo, and now bondo hair, if that tells you anything.

I've read a couple things online, about using resin, mat, cloth to help join body parts. I don't know where to get this stuff, or any brands that make it.

Help me out? Page 5 of this thread shows the vent I'm using.
Hood Vents / Louvers

I want to mold it into my stock 04 hood and fill the stock crevices coming down the hood.

I need help and ideas. What should i use, and where do I go to buy it.

So, you're trying to make that vent look like it was formed in the hood?

i would use rivets and glue(duramix) to hold it in place and then just smooth it over with bondo. it will be a lot of sanding, then prime paint and celebrate.

I remember I went to autozone and got a big container of epoxy resin. It's a bitch to sand, but very strong.

Bondo will crack.

Don't use Kitty hair, its thick and provide a mess that you'll have fun trying to makeit prretty.

Fiberglass mat and fiberglass resin. A wire brush, coarse sandpaper



Basically sandwich a few layers of saturated mat between the roughened vent and wired prep work

I warped a carbon hood by fixing the cracked frame structure on the bottom. The car was in a wreck so the support on the driver side was busted. I fixed it, and it looked great, but the fiberglass epoxy stuff or whatever warped it. The hood wouldn't close all the way on that side. Just putting in my .02 and all.

If you mix it hot, that's exactly what it will do... if its mixed on the long dry, it'll be ok

What's on the long dry?

more hardener = faster dry time = HEAT!

This... less hardener, long dry time, less heat, no warp

So some of this makes sense... Lol. Where do I get this "mat" you speak of? What kind of resin/ epoxy should I use?

Pretty much, I might as well. I wanna fill those crevices or else it might look weird

I'm going to watch this thread, I want to kinda do the same thing, but to mold my lip to my front bumper.

Good fiberglass resin will work, which you can buy at wall mart/autozone/oreillys/pep as well as the fiberglass mat.

Anything of this caliber depends on prep, anything of molding fully depends on prep

Sweet I just got a Walmart gift card. Lol. I'll probably swing by on my next day off and see what I find/take pics of the stuff

How do you think this little kit looks? Should have everything I'll need?
Buy Bondo Fiberglass Resin Repair Kit (1 qt.) 422 at Advance Auto Parts

"Bondo® fiberglass repair kits have everything needed for the do-it-yourselfer, including simple directions, fiberglass resin, liquid hardener, plastic spreader, fiberglass cloth, mixing stick and a mixing tray. "

sammy, skip the kit.

buy resin, hardner (7 drops per ounce of resin i think) cheap paint brushes, and fiber glass mat the chopped flavor not the woven like carbon. cut the mat up into 1 or 2" squares or strips or whatever you think the situation will call for. cut plenty as you dont want to stop glassing to cut more. mix resin in a small food container like a cool whip bowl or something of that size. mix up a few ounces to get a feel for what you are doing. when you notice the resin starting to stop working on the part because when it starts clumping it creats a lot of sanding. roll the clump around in the bowl to get out all of the resin you can and scoup up as much resin as possible with the paint brush and stick it to a tree or somehting. use the paint brush to dab the resin into the cloth instead of the spreader. the spreader will make resin run all over where as the paint brush will absorb the excess and itll push resin into the mat.

while you are add it use excess resin and fiberglass matt to get rid of the bucktooth on the grille its actually a very easy process just time consuming mainly wait time and sanding

Thanks for the tips, I'll see what I find at walmart/advance auto parts today.

I also have pnumatic orbital sanders, sanding wood is what I do for a living, so the sanding part should be easy. Lol.

was going to say invest in a good sander you will need it haha
