RE: Painting My TF P 51.
Minwax Polycrylic can be used over the latex with no problems.
Polycrylic is FUEL RESISTANT with the following caveats:
1. Let the poly dry for a MINIMUM of 7 days before exposing to glow fuel residue (wipe raw fuel off right away )
2. Do not let the residue remain on the finish for longer than 4 hours. After 4 hours the finish will soften.
