RE: Don't paint the tips!!!
For those who're afraid of paint on plastic props, consider this..............
In the last few years, at least one paint mfg has marketed a line of "plastic paints". You'll find it in the "paint in spray cans" area of most home improvement stores. The closest Home Depot has a couple of colors, white and black. The Lowe's Home Improvements have a couple of different lines with 6 or 7 colors.
The paint is supposed to "bond" with the plastic and "become one" with it. I've used it before and it appears to be fuel proof. Truth is, most enamels are decently fuel proof if you give them enough curing time. But this plastic paint sounds like there is a bit more to it than what happens with regular paint, enamel or lacquer or whatever.
So if you're planning to paint a plastic prop, you might consider "plastic" paint for the job.
