It certainly did!did it rain there? It rained here!
Stupidly I fell into the trap of trying to rush the painting yesterday while the weather was good. The end result is that I got the black paint on perfectly then mucked up the clear coat and got a run down the front of the dome. I was furious.
Now I'll have to wait for it completely harden before I can rub down that area and recoat it. That'll be a week at least. More haste, less speed.
