I tried some acrylic craft paint from our local Hobby Lobby store. I clear coated it with the local house brand of two part urethane automotive clear. Hobby Lobby paint dried for 24 hours and brushed on urethane. I just needed to touch up under the spinner on the cowl so didn't need to spray anything. The urethane was laid on pretty heavy so if a reaction was to take place I would have thought it would do something. While not a definitive test, I'm happy with the results. I'll try it again on a slightly larger scale next time and spray everything. Over all it looks promising.
