Re:Fiberglass Molds
Well I do it the home made way. i used celophane. I just strech it over the part I am making a mold of but it has to be shinny or it won't stick. I will have to go to the auto body store and get me some of that stuff so I can make these more complicated molds.

Re:Fiberglass Molds
I have a lot of experience with glass. Check out the yellow car on my web site www.speedpartsrus.com . I hand layed the whole thing. Couple of things right off the bat. Wear a respirator and gogles. The activator in the glass resin causes pernmanent blindness if you get it in your eyes. The fumes cause all kinds of health problems as well as neurological ones.
The main problem with making parts out of glass is the shrink factor. If you make your mold out of fiberglass it will shrink as it cures so now its a little smaller than the original part. Every part you make in that mold will shrink and be smaller than the mold.This will cause larger parts like fenders to shrink as much as 1/4 inch overall. This is why cheap body kits dont fit. There are some good books on the subject.

I will work on the guage pods this week sometime and I will see about the $5. I haven't made them yet do I don't know
There is a market for it.... HUMMMM
??This might be big, but somehthing to connect the center council and the dash board, right in front of the ''drink holder'' and under the radio
Make some inserts, take out the radio and maybe the climate control...

Re:Fiberglass Molds
I think that the yellow car is real ugly. Why would you buy that thing. Is for a saturn. 
But really, I didn't know that the fiberglass shrunk. I have never had it shrink on me. I bet that you use inferior mat like the pressed mat that has randon fiberglass all over it. The weave mat looks just like the carbon fiber weave. It is easier to work with and you can layer it in differnt spots to give different thicknesses.I will make something and show you what I mean. Oh and the parts that I make will be painted black to match your interior. If its any other color then your a ricer and it will still come black. Don't worry you won't be able to tell if it is plactic or painted. I have the right paint to make it look right.
