Just bought the primer for the frankenfiero, and sales clerk said i had to use a hardner for it, using 2k. Is thius necessary, or do i want to keep the paint flexable. and if used what is the mix ratio, as the can doesn't say.

If you got 2 part primer, you HAVE to add the hardener or it wont ever dry. Very few paint cans have any instruction. You have to ask the clerk for a ' product data sheet ' that tells you how to mix and spray it.
All the body parts are solid enough any paint on them will flex sufficently. Nothing special is needed. On the soft bumper covers, you either have to use waterbourne primer (expensive OEM stuff) or just spray any primer on very lightly. They say 2 part epoxy primer flexes too, but your on your own there. I wont use it at all. The key is not to build up much thickness or it will crack. Flex agent added only stays there before it evaporates in a week or two to allow you to reinstall it without cracking it. single stage or base/clear coat paint flex enough not to worry about it. I prefer the soft bumpers mounted to paint them. If they need color on the edges, i spray the edges, then mount it, paint with the rest of body.

I'm hoping that you are going to remask the car when you are finished with the primer. Using newspaper as masking paper will give you all kinds of problems. Newsprint is made up of very small fibers and when you spray your primer/paint you end up getting those fibers in the air and all over your fresh paint. With primer it isn't a big deal as you are going to be sanding everything anyway but when you paint that newspaper will really mess up your paint job. You need masking paper designed for automotive painting that you can get from your paint shop.
