Loren:

I have (had) a few sags in the last epoxy coat on my nearly-complete Northeaster Dory. I used 220 grit pads in a oscillating power sander to lower the sagged line down to base coat level, then I recoated. If it worked in epoxy, it should work in Brightsides or any other covering. The re-epoxied surface looks like a mirror.

My experience with Brightsides is that it does not buff or polish well and you must plan your overlaps as it will not feather out for touch ups. If you must, I would use a cabinet scraper or razor blade to scrape away the high spots and then try to buff out the scrape marks. I think you will find that it would best if left alone, after the first scratch it will not matter. Depending on who you ask; two foot rule, three foot rule, five foot rule ;-) if you can't see it from a few feet away it does not count.

Brightside does not like to fair out well. I have been able to get around it by using a razor scraper and getting it flush. Then let is cure for a few days in a warm environment.  I then picked up a Preval sprayer. Use 216 and thin the brightside and lightly spray over the area fairing it out a ft. or more. Let dry completely then buff with 3M Fenesit.
