Absolutely stellar work - I aspire to your obvious skill. I have been toying with the Spray Max 2k coatings. They have a crystalline clear spray 2 part - I am using it on a Parenthesis to bury water soak labeling on a custom Hammond box to tremendous success. It's expensive and the spray can pot off in less than a day, but imo it's worth exploring.
