Confused on Clear Coating Latex
I tried water-based Polycrylic as a final clearcoat on my latest plane and it softened and caused the latex underneath to bleed when I spilled some raw gas on the cowl. Made a mess. I cleaned it off, touched up the colors, and applied Minwax satin OIL-BASED and it's fine now, although it yellowed the white areas somewhat.
The water-based Polycrylic worked well for glassing, but don't use it as a final clearcoat. Use the oil-based as a final clear. I'm speaking from experience. I've used the Minwax oil-based clears for years on gassers with no problems. You just have to put up with the yellowing effect.
I would give it a couple of days cure time before subjecting it to possible gas spillage.
