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.

Thanks for the great advice.

Yes, this will be my first time working with fiberglass. I'll be sure to take all the necessary precautions and get good EQ before I start. Also, I'm in no rush so this will be a weekend project that will stretch over a few weeks (possibly months). Basically I want to get some experience with fabricating parts (and have some fun while I'm at it too).

I've got a good piece of foam...should I get a heat gun to shape it (was confused on that point)?

BTW, I might pickup some cheap after market bumpers and cut it up into pieces just to get a feel of the dimensions and shapes that can work.
