I don't see why you can't scrape the drip, scuff the thing down, and then repaint it. It's not House of Kolors Kandy, it's just rattle can paint.
You shouldn't gob it on, even if it's hammercoat. Your first coat should always be a light dusting. Then when it's tacky, go with multiple light coats to avoid runs, rather than one heavy thick coat.
What have you got to lose? If it still doesn't turn out nice, then you can take it all down to metal and redo it.
And perhaps go where the lighting's a lot better.
