lol@making dust. As a powder coater I can only offer this..... even the BEST of clear coats (even in the powder world,folks) degrade over time. It may take a lot longer but then again..... it's a royal pain in the you know what to strip it down and repeat steps 1-937,245 if you catch my drift. Zoop looks like a good sacrificial top-coat if you will. As for the VHT.... I simply have no experience with it so I can't offer sage advice,sorry

. Your query is still fresh so I'd give it a little time. I'm sure a lot of people have done what you have and will no doubt offer some good advice. Good luck with it.... Russ
