Skipp, I was also surprised by your problem with the Krylon clear spray. I have also been using the clear UV-resistant Krylon #1305 spray (NOT the regular stuff)for over 45 years on both my ham & commercial installations without any problems. The UV clear spray is usually a special item available only from Art & picture frame distributors. It's usually NOT found in your local hardware or craft store. Even the UV stuff will eventually crack/flake off after many years. I believe the only thing that has changed in the formula, over the years, is the propellant used. YMMV.
