Geoff,

in the future always apply the first coat of product thinner so it adheres properly. Always apply coats that go on wet and shiny for proper adhesion. Additional coats can be applied to build the thickness of the primer to fill surface imperfections. After primer has dried but before sanding use a guide coat. A guide coat is a very thin spray of a contrasting color primer. this primer could be from a spray can purchased at the auto parts store. Compatibility is not a problem as all of the guide coat is going to get sanded off to make the primer smooth enough to paint over. While sanding, the low spots in the panel from scratches and imperfections will show up becaust the guide coat will still be in the little scratch or imperfection until it is completely sanded out making the old question of wether you have sanded enough answer itself.



Good luck
