My source for Rustoleum gray auto primer has dried up 1 can short of being done with primer.  Can Krylon gray auto primer be used in it's place and most importantly, can Rustoleum color be applied over Krylon primer?

Never mind.  I went ahead with another shade of Rustoleum.

Will it go between coats of Sig dope?  I am refinishing an old stuntship originally painted with Sig dope.  I've sanded it down and repaired spots as needed.  Now I am trying to repaint with more Sig and having all kinds of problems - particularly at any edges where I sanded through the old finish.  I'm going to sand it down again and use something other than Sig, at least until I get some isolation from the original surface.
