[QUOTE="DaleH, post: 474508, member: 15636"] White vinegar and a copper scrubbie pad is certainly cheap enough to acid etch any bare spots. For better results, a $9 spray can of zinc-chromate primer should do any bare tin you need or want to - IF it is to be top-coated with other paint. If not top-coating, you could skip the Zn-Cr and whomever told you that you could 'prime' tin with epoxy was flat-out wrong ... as no 'bare' tin should be painted over or gooped without being properly primed IMHO. I personally use the 2-step method of vinegar wash and then Zn-Cr prime. Just half an hour ago, I [i]just bought back[/i] an older 14' Smoker Craft boat that I had sold a kid 10-years ago. It was rebuilt by me using all the tricks I've posted here through the years and it is as sound today as the day I sold it. Done once ... done right! [/QUOTE]
