need advice on how to do that, after all dents and rust are taken car of how do i proceed to strip paint and reprime car?

 

To strip it down to metal, you need to get paint stripper. You just wipe it on and wait about 20 minutes, then you scrape it off. This is a very tedious process, but it will give you the best final results. Once you finish stripping it, you will probably need to completely finish it by sanding off any leftover paint. You need to wash all of it with water to neutralize the stripper. I would then rough up all of the bare metal with 80 grit to give the etching primer a grip. After sanding it again, you need to spray it with etching primer, Dupont's Vari Prime is what I use. After the etching primer, you need to spray it with regular primer(gray primer--I use laquer primer) and there you are.
