Painting tank screw up

[BCOrchidGuy]

I've done it, clean the glass well with vinegar and water or alcohol (rubbing) and make sure it's good and dry. I've only ever had trouble with the paint when it got water under it. I've also used tremclad spray paint and if you do a super light coat and then a bit heavier and a final coat you'll have to fight to get it off.
Just clean off the old paint with a razor blade (be careful). make sure it's good and clean before you do any more painting.
