So I contacted TCP Global. They assured me that #9381 was the correct product for my hood stripes. I was relieved (for a while) feeling like I had found a solution to my problem. When I talked to my body guy (who has considerable experience and ran his own shop for 40 years), he adamantly said that he wouldn?t spray acrylic lacquer over hardened Urethane. He claimed that it will wrinkle and he just wasn?t going to do it. I have had a forum member reach out and tell me that he has done this exact process many times without any wrinkling issues. I called TCP Global and asked one of their tech assistants about this issue, and he said that this is not an issue that I should be concerned with. He said the only time that I would have a problem like this is if I sprayed the Urethane over the laquer instead of the other way around. I am not a painter, I don?t feel that it is my place to argue with an experienced painter. Can anyone else weigh in on this process? Your experience?
