Alright, i have a 91 crx si and it has well... lets say a lot of body work to do. Rust repair, door line filling, body kit fitting+molding, etc. Now, I am planning on using kitty hair(short strand waterproof body filler) for almost all of the body work, fixing the door lines, etc. then putting the lightweight body filler over that. then topping it off with finishing coat. I do not plan on using regular bondo at all because the crap sucks. period. it cracks and just sucks. I want to take off all the old bondo and then primer the whole car, then start doing all of my body work.
If I spray primer, Do I need to sand it off before I can put more body filler in, or can I put body filler over the top of the primer? Without having paint lift or anything like that?
So here is the visual of the layering
Metal / Fiberglass
primer
body filler
more primer
body filler
lightweight filler
top coat
primer
paint
Basicly, will the body filler stick to the primer just as good as to bare metal?
..or do I need to sand the primer off and put the body filler on the bare metal?
