Today, I painted the right wingtip red. After taping and a bit more filling, I gave it a coat of primer, let it dry, then added a coat of white, and two of red. I used the quick dry thinner. Unfortunately, it didn't dry. I finally realized I had mixed two thinners in with the paint and forgot the activator. Ugh! So, a bit of MEK and I wiped the wingtip dry. I'll have to wait to finish it after an upcoming trip. I found the same thing on a bit of touch up I did on the leading edge.
