I found this "etch primer" in rattle cans. What about overspray, blending, should I go with an expoxy instead. I plan to sandblast and at least prime as I go. https://buyat.ppg.com/refinishProdu...tID=63817403-97a9-4ec8-98aa-d5ac0fb87258 I do not get a lot of time at home and most work is done on summer break 2 weeks or so at a time.

I have had rattle can primer lift when the top coat is applied. Try the rattle can stuff, but then a sealer over it before any primer/filler or top coat. I also don't completely rely of primer/etcher to make sure there is no rust buried. I first wash the exposed metal in a rust preventor, and then I prime. In any event, remember that primer will not hold up very long against oxidation penetrating it. | | |
