Urethane primer and body filler
The cab and fenders of my '51 GMC are currently in primer. It had an etching primer sprayed on first followed by Nason Urethane primer.
The parts need some minor body work; minor enough that I figured I would have the parts blasted and primed so I could do the body work over the primer and not worry about flash rusting. Well, it was supposed to be epoxy primer but I'm not going to go into that right now.(The remaining sheet metal has been epoxy primed)
My questions are:
What are my options for applying body filler?
Must I sand the effected areas down to bare metal prior to applying filler?
If I sand down to bare metal, should I use a self etching primer? Can I apply filler over that?
Can I scuff the urethane and apply filler over it?
I need some guidance. Any help would be much appreciated.
