When I bought my Hunter 26.5 three years ago it had a fresh coat of VC-17 on it (the survey said so). After that initial season sailing on VC-17 I subsequently applied two coats(seasons)of ablative paint(Interlux Bottomkote). Now, of course, I want go faster want to go back to VC-17. Why can't I just power wash off the remining two seasons worth of ablative and reapply VC-17? Doesn't ablative paint, by definition, wash off with water?
