BAH!
I can't win.
I'd built my Vulcanite without a launch lug for launching on a tower. I decided to add one. After that I needed to repaint it. Rather than the same (pretty nice) gloss blue, I decided to go with cobalt metal flake and clear gloss coat.
The temperture got over 80 and the humidity got below 60, so out I went. What could happen? Both dry in like 20 minutes.
An hour later, all dry and ready to bring in, and I discover.....
dandelions. Fuzzies had glommed onto my paint and turned into cobalt blue and clear coat boogers.
I don't HAVE dandelions. I can't see any anywhere.
But, apparently 60% humidity is just fine for Rustoleum metal flake and clear gloss. Except for the boogers, it looks good. I took some pics. I'll post them when they're processed. Boogers and all.
