In doing my research and relying on Tom here for a lot of questions I have
had on my 50 frame-up project, I ran across a really nice product from
Sherwin Williams called self etching primer/filler. Has the etchant
qualities yet is also sandable and builds on the surface allowing you to
really get a smooth finish before applying epoxy primer. My question is,
epoxy primer isnt normally sandable (from what I understand) and this seems
like a bad thing since its recommended after the etching primer. Is there an
epoxy primer that IS sandable before applying the urethane top coats?
