Paint for underside of the car?
I have the ability to do this myself, but I am by no means a professional painter. What would you do? Throw some flat black on it and call it a day? Scrape it down myself and try to put some matched paint on it? Let a pro handle it?
Thanks for any and all replies.
-sandblast/sand away the rust (you must get every little bit!)
-paint over it using whatever paint (flat black is fine)
-spray the whole area with several coats of rubberized undercoating
The undercoating is a must, because if you just paint it, any little rock chip, or ding is going to rust. Rust is like cancer, if you don't sand it all away to raw metal, it will bubble back through the paint eventually.

I am thinking the Eastwood rust encapsulator rolled on may do the trick but ask.
If this were just a beater, I'd give the rust a quick scrape down and then flat black over it. However, I'd like a little better for my car. It's still a daily driver so I don't think it's worth have a professional prep and paint the underside (yet). I'll probably try to find some matched paint then sandblast the rust/area, prime it and paint it. I might add a layer of undercoating and then another layer of matched paint. I haven't decided.
THanks again
