I used the K-36 over UV smooth prime to seal it and am going to do my
flyoff in this condition. The coating was good and it stayed pretty
smooth. I used a HVLP gun and did not have good luck with it. However
going to a normal spray gun led to better results. I did have a good deal
of sanding to do but that was due to me having 4 thumbs when dealing with a
spray gun. The sanding left me with an entirely acceptable finish. I
believe I used grits between 360 and 600 both wet and dry.
