Guy's I am gonna use one or the other in finishing a new model, and I want to know if yellow & black in each of these brands will be fuel proof/resistant?
 
  Thanks a lot...

Rustoleum Gloss Protective Enamel will be.

I can't speak to Krylon.

I second that.

it's been my experience that Krylon is not fuel proof.  I still prefer it since I always clear coat it with Nason two-part.  It dries so much faster and i like most of the colors better.  But that's just me.

Sparky pointed out in a recent thread that Krylon has changed their formula.  They used to sell laquer, but they've changed to enamel for better conformance to environmental regulations, at least with their "consumer" paints.

Soon we'll all be painting with watercolors.  Does anyone know how fuel proof milk paint is?

  Thanks Guy's, That settles it I am gonna go base/clear coat.
