corvette body work

[RobM]

just bought a 71 vette and I want to do an exterior restoration just have a few questions,
I have been doing body work professionally for many years I have done several high end Porsche builds so I know what it takes to do a top quality restoration but i was wondering if there was any thing special about the substrate on a 71 vette, I have heard things about SMC being used in c3's.... was is used in this year? can I use normal body filler to skim the panels? what kind of primer should i use? Can i use a normal high build poly primer? I have heard of people using gel coat to hold down the body work? the car has no damage other than stress cracks and its wavy i want it perfect straight and black...

I can do this with a normal car i just don't know what materials to use on an old vette i have never done a corvette... I don't want the car to look good in the shop and then turn into a mess once is gets hot in the sun.

need some PROFFESIONAL opinions
