How paint over removed rust?

[GerGa]

Hi, I am putting a hitch on my 04 Buick. There is a small amount of corrosion started on the "frame" surface of the car where the hitch bolts up. Not a lot but a little. Before putting the hitch up, I would like to strip and repaint, just to slow corrosion a bit. Also these hitches tend to rust.
Heres a pic of the hitch:

I'm not sure the ideal way to repaint, though. Primer, rust reformer, etc?

I was also thinking of using an automotive sealnt like this Loctite 5200 marine sealant between the hitch and car, but on another forum someone suggested that even with a sealant you could end up with a hole somewhere and harbor stuff crap, and they might be right especially with the bolt holes. http://www.amazon.com/gp/aw/d/B0000AY6AC/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=A297FB27E4KSS3

Thanks

I would sand down to bare metal, apply a good uniform coat of primer and paint it. I would even apply a couple coats of clear as well.

I was thinking the same thing--keep it simple, primer, paint, even a clear coat to top it off. Good to hear my thoughts reflected.

For a frame or part of, try a product called Zero Rust. Search the autobody forums for info. If you need a link to one, PM me.

I would sand off any loose rust but not necessary to go to bare metal if you use a rust converter primer. Correseal (not sure on the spelling) converts rust so it stops rusting. It also is a primer so it turns black on rust and clear on paint. Let it cure for 24 hrs before you apply paint. Best thing I have tried with 3 years trial of durability.
