During my rebuild process (finished 2 complete rebuild Johnson v-4 crossflows), As everything was disassembled I painted each piece, including the block, and also applied new cowl decals...... This was a painstaking process.
Not so much the cowl or exhaust housing, but the Engine "Pan". Everything on the other motor parts were sanded rough, then up to 1000 grit. However, the pan has alot of Nooks and Cranny's which makes it hard to sand(as does the TNT/bracket area)
Does anyone know if there is a self etching primer that adheres to the existing clean paint well, thus, makes the topcoat adhere properly?? No sense in spraying on top of shiny existing paint as it will eventually come off.
I've used Rustoleum regular primers, or Zinc Chromate on any bare metal, then Multi-coats of Rustoleum topcoats and the results have been terrific .... but on my current project, I want to reduce some of the time on the Pan, and I will be using my Automotive sprayer and compressor.
Thoughts.
