paint runs
You can't expect to be a pro first time out.
Painting is part science and part art....throw in some luck, timing and patience.
Nothing like running the air hose against a freshly painted panel, or a making a butt-print...or just plain old having a fender fall onto the ground becuase you didn't hang it up secure enough. Been there and done that.
Years ago I was painting my Belvedere's roof on my parent's driveway when a freak sun shower hit and rained on it.
My first base coat / clear coat paint job...the paint place sold me the wrong clear coat and it crinkled the whole paint job...so much for consulting experts...I had to start all over.
I would wait and sand it down and give it another go.
