Well, ready for relaunch tomorrow. I learned a few things that might be useful to others. 3 weeks full time work for one...
September is probably about a month too early for outdoor painting. The nights (especially one - the most important one!) can be too cold. If the temp drops to dew point (actual temp depends on humidity and pressure) the gloss is lost. I lost some gloss in places on the hull due to this. Really I should have done a 3rd topcoat, to fix it, but no guarantees that would come out any better! So it is what it is.
