While washing the front of my 2016 Starcraft 19.6 I noticed a number of small hard mould like growths that wouldn't wash off. They are on the curved part of the front of the van only and difficult to photograph. I don't want to try and scrape them off as I'm afraid that I'll damage the gelcoat on the fibreglass.
Does anyone have a way of removing the damn things with out damage to the substrate?
