Well the results are in! You can overcoat the new "Fusion" paint with clear Lustercoat to fuel proof it, but you need to wait severals day to let the original coat cure. I waited the 7 days that Krylon recommended and applied several light coats of crystal clear lustercote over it with excellent results. As an experiment I tried to overcoat Fusion with Lustercote after only waiting several hours and it did attack the base coat, so as long as you wait and let it cure properly you should have very good results. I can tell you that this new paint sticks to polyproplyene better than anything I have seen to date. After several days you can't get it to come off! I bent and flexed the plastic trying to break it loose and could not do it.
