Gave this a second thought and had another thought to share... Unless you're planning on good auto grade clear coat, I'd skip this. Go get any brand of rattlecan clear ya want, spray half of something that's a nice bright white, then wait a year, two, or three.
All the rattlecan clears I've used will all be yellowed in a year, and have a brown hue within a couple years, no matter the care given to it. I'm yet to have found a rattlecan of clear I will use on anything that I want the colors to remain bright on because of the nasty brown tint stuff gets with rattlecan clears. That's why I've became such an avid fan of Rustoleum paints, it's lasts the best, looking the best, and ya can normally find a match for anything.
