I'm finally getting ready to paint the interior of my RV-8A QB fuselage. Van's (Philippines) coated the interior with Sherwin Williams P60 G2 wash primer. In several places, I need to re-prime the interior aluminum where I nicked/abraded/sanded away the existing primer during the building process. Also, there are several areas of the primer with air-tool oil on the surface.
I'm thinking the following:
1. Wash the entire interior with a no-residue soap solution. Rinse with distilled water. Blow-dry.
2. Scuff primer touch-up areas (only) with Scotchbrite. Vacuum/remove Scotchbrite residue.
3. Clean touch-up areas (very lightly?) with lacquer thinner. (Probably removes some, or all, of the existing primer as well, but I'm planning to re-shoot/overlap anyway.)
4. Apply Sherwin Williams GBP-988 rattle-can primer to the touch-up areas (or some other rattle-can primer? - - Please Specify). (Overlap existing P60 G2 wash primer at the edges.)
5. Paint over the interior primer(s) with a high-quality, rattle-can enamel. Allow plenty of drying time and accelerate enamel hardening with heat, as possible.
As you can tell, I'm not planning to shoot the interior with my paint gun. For me, the paint-gun process is too much trouble for the interior so I'm attempting to go with some sort of rattle-can primer for wash-primer touch-ups. I plan to apply Dupli-Color or Rustoleum rattle-can enamel over the interior primer(s). For the exterior, I'm going with a paint-gun-applied, epoxy-primer-acrylic-urethane system.
Well, anyway, I would appreciate any suggestions regarding the proper rattle-can primer and process to use for touching-up my Van's-wash-primer QB interior.
THANK YOU!
