Try Spray Max 2K Epoxy Primer in a Rattlecan...
Recently purchased two cans of Spray Max 2K Epoxy Primer PN 680032 from Eastwood; sprayed bare metal trunk compartment in a mid-engine exotic because I needed a paint that wouldn't disolve from a drop of brake fluid. Spray Max 2K Epoxy Primer spray nozzle worked exceptionally well, layed down a very nice even coat which curred overnight. I will definitely be using this paint again... Was very impressed with results. As good as any professional spraygun, without the cleanup mess.
