RE: cresting

The best advice I can offer is to try it and let us know how it works out for you. Not too many people have a lot of exposure to automotive paint (or choose it as a substitute to just spray paint). Just strip an arrow down and give it a whirl, you may want to try a couple different adhesives, but just about any "should" work, unless they have some sort of ketone or acetone base, which I don't think very many have.
I just use regular super glue on every, and it works fine, lol.
