I read often online in various discussions about people who say you can't paint over steel that's been treated with phosphoric acid because it will "blow up". I take that to mean the top coat fails in some way. They may be correct..................in their situation. My guess would be they didn't do the full process or didn't do it correctly and left some residue behind. Cleanliness, make that absolute cleanliness, is the "secret" to good refinish outcomes.
Uncle Bob, I'd like to hear more about this phosphoric acid rust treatment, whether here or somewhere else if that's too much of a hijack for this thread. I have a few rust bubbles near the rain gutter on my '66 F100 that definitely need some attention. I'm hoping they won't require major surgery but in the meantime, an effective treatment would be helpful. Thanks!! Great thread, guys!
