Jus sprayed the GT-R, bad stuff happened...

there are bubbles...like paint bubbles, about 3 of them, and some dust....what can i do about it?

Next time when you see bubbles in your paint job, and if they're still wet - very important - you can poke the bubbles using needle / thin wire. It'll release the gas and hopefully the paint will even out. It works for me.

If everything's dried, I guess you just sand and maybe repaint the area.
