sanding body

Is it necessary to scuff up the body before primer? Do you have to do this? I sand off the mold lines and all of course. I'm going to paint my Vertex RX-7 soon and I need to know. Sometimes I use the Testors 2 part lacquer system and its not even necessary to sand or prime at all, just color and clear. Thanks for clearing this up for me! "Please excuse the pun" :)

I usually sand it very softly with very fine steel wool. It works great and primer adheres better.

I do, primer does adhere better like cold fire stated. You don't have to do it, but its recommended. What ever floats your boat buddy.

i am at the same point would a light sanding some 600 grit suffice?

600 is good for body flash and mold lines, 800-1000 is what i use to sand down a body before primer.

:1: that's what I do too.

Thanks for the great information guys! Now, if I can only figure out how to paint those damn RX-7 tail lights, I'll be in business.
