Hi Al, Might have been another brand of paint but I bought mostly Krylon because it was only $.99 cents a big spray can for many decades. But the clear spray paint did something to the antenna to make it unusable and I still have it here. The issue is how a person should first try to investigate the properties of sealers and paints for RF issues before they hit the same brick wall.
