While it is a faux base coat/clear coat job, for a sport jet like my HotSpot, it works fine. Used to paint Giant Scale cowls and wheelpants this way.

The base coat is Krylon, your choice of color. Several THIN duster coats. Don't worry about the shine. Wait for 48 hours for thorough setup at 70F or above.

Then wetsand with 1500-2000 wet paper with just a drop or two of dish detergent in the water.

Finally, shoot 1 coat of polyurethane exterior clear (I use ZAR brand from True Value--no isocyanates, and about 7 bucks/pint)
thinned 1 part mineral spirits to 4 parts clear. Any more than that and you start to have blushing problems if the humidity is more than on the surface of the moon. Bright appliance whites many yellow slightly, but it's hardly noticeable. No effect on any other colors.

Then the hard part. Wait 5 days for thorough drying at 70F or above. The flat surfaces dry fast, but any excess clear around curves takes a long time to dry.

Then, if you are like me, you're done. Go Fly! My sore rotator cuffs and tennis elbows can't take too much polishing anymore. But, if you are up to it, wet-sand again with 1500-2000 paper, and hand-buff for the next two days with graduated 3M cutting polishes, for that possum poop shine!
