Since you are using Rustoleum products on this respray, that is odd that this happened however, I have called the 800 number for Rustoleum (a decade ago) and have gotten good advice that went beyond just the original question that I asked. The rep' was helpful. I don't remember the reason for the phone call, but it might have been similar.

Rustoleum small projects: 1-800-481-4785

Rustoleum Automotive paints: 1-800-585-8430
