Imron Clearcoat Repair

Q. 3 years ago I had Imron clearcoat applied on my varnished hull wooden boat. It is beginning to get dull and there is a spot where the boatyeard sanded a section (thinking it was varnish). Can I just re-spray the entire hull or does the old coat need to be removed first?

A. I don't think you need to remove the old coat, but you certainly need to thoroughly scuff sand it and wash the entire surface to remove all remaining sanding dust. I suggest you do not do the entire surface all at once. Rather, sand a section, wash it down and then repaint it. The goal is to get the fresh clearcoat on before the sanded coat can oxidize in the air.
