Ok, no acetone next time. That is what was recommended for Eternabond so I thought that would be right for final cleaning before applying Heng's. But people seem in agreement that I rushed the job or screwed up the prep. I'll study the Hengs instructions carefully and try to contact somebody at the company for advice. And I'll do a sample area first and give it a month to test it.
No I didn't do it all in one day. More like 3. But it was somewhat faster because I did not remove any roof structures like vents because they were already well protected with Eternabond so I only recoated up to the Eternabond or slightly beyond.
I have never been a fan of Eternabond for sealing vents or other roof penetrations. That is what Dicor self leveling caulk is for. I know Eternabond tape is super sticky, but putting tape over irregular surfaces just doesn’t make sense to me. I see it as great for an emergency fix to the flat rubber surface, but not over screw heads, and uneven surfaces.
