I figured i would compile all the info on this and put it in one subject for everyone to see.



This one is on making molds(originaly posted by Rob x-7):

You will need some mold release wax,gel coat ( tooling and regular gel coat) , resin, MEK, fiberglass matting,and some wood or something else to stiffen the mold before you release it from the part so it doesnt lose it shape. You will also need rolling tool to roll the air out of the matting as you go. You will need different weights of matting.



You have to polish the part to a high gloss, put about 3-5 coats of mold release wax on it, wiping it off with each coat.

Spray the tooling gel coat on it, you will need a special gun to spray it as normal guns cant atomize the gel coat unless you thin it, and you cant thin it if you are using for a mold. Then when that kicks you put a layer of 3/4 Oz matting on wetting it out with resin, then when that kicks you put 1.5 Oz matting on until you achieve the desired thickness of the mold making sure

to only put about 2-3 layers at a time so the mold doesnt get too hot.

Then you add stiffners to the mold before you release it.



Some notes:

If its a intricate part you may have to put a hole in the mold to blow air thru the mold to get it to release.

Make sure you dont set the resin or the gel off too hot because you can distort the mold.

You dont have to spray the gel coat in, you can try brushing or rolling it, but chances are a few months down the road when the part you pull off the mold sits in the sun the brush or roll marks will show thru the primer and paint, this also happens when you put wood or balsa core in the part as well.





I'll keep adding more info here as i dig it up.

Thanks for posting the info I recently bought the mold for the FC3S version of the GTC front bumper that was discontinued that everyone wants one I want to make some copies. Mad people want one and there was only a handful made I believe, like 5?

Rob x-7

im sure if people wanted them they would have sold more, they probably

only sold 5 because people are usually all talk until it comes time

to hand over the money, then they turn cheap.

RACEX7

I am well aware of the fitment issue but most of the forums I visit there are 5-6 people that want the bumper really bad. I don't intend to sell the GTC front end at retail price maybe 400 each.

Rob x-7

what price are you thinking of selling them at?



there is always 5-6 people that talk like they want one, then you will

be lucky if you get 2 total

What type of gun do you use to apply the tooling gel coat with?

Rob x-7

a gel coat gun, cheap and messy

I've never seen mold release wax.Would a body shop know where to get this stuff from?I think I might need to make some spare fiberglass body panels.Where do you get that gun from???





Thanks
