If you just paint over it, the rust will spread, and will bubble your paint. If it's not much, try Naval Jelly and see if that gets it off.Daft said:I guess the best thing is to sand it off, treat it, and paint.
What if I just painted over a really small little bit of rust?
Will that rust spread even if I painted over it?
I can sand that down if I really need too, Thanks for any advice!
