Too ambitious?, Want to make my own body kit. Options

[CAMAricer]

I guess the first thing to do is make molds of my existing parts to use as a template...

Does anyone know what kind of material I need (or will need) to do this? What's the cheapest practice material I can use to learn how to do this? Thin aluminum sheets? Foam boards? Paper mache?

And where is best place for me to shop for fiberglass, carbon fiber sheets, etc?

Just last week, I used bondo for the first time and it seems to me that with enough practice (and money), anyone could create their very own body kit out of these materials.

For making a mock up i'd use a very hard foam that is able to support several times its own weight, so as it doesn't deform easily.

But then agian if you're going the whole hog, why not get some second hand bumpers and custom fabricate the kit rear end front using these as a starting point, build it up with the foam i mentioned then cover it with fibreglass to make it durable.
