I went with the longer curing, as I hoped it would self level a bit better and I wasn't in a rush. Although I don't think it really leveled itself at all. It was necessary to do it mechanically.
Doug what was your technique for applying the Anti Bond 2015 did you simply score the surface then spray? Does the old stuff just peel out after, or is it still a huge amount of digging and scraping to get it out?
Although I didn't use the 2015, as it wasn't available in town, I did use another marine de-bonding spray and it helped a little but I wouldn't say it was superb. I scored the top of the old sealant, and ran a razor down each side to help the liquid seep down.
