After a light coming together with a mast a couple of weeks ago, one of my hulls has a longitudinal wavey pressure indentation about 3 feet long and half an inch wide. It appears to be a pressure mark rather than scraped/scratched - or so it seems to me - still mirror smooth. It's obviously not invaisive damage but looks ugly - and looks impossible to fill because it's so shallow - probably about .5mm, if that. To rectify would I have to make it deeper and then fill or is there some magic wand I can wave...? It's an Auscat Mk5 Flyer made from carbon -> kevlar -> gelcoat. In fact I keep noticing pressure marks all over the hulls which surprises me; I never noticed such marks on my Dart 18...
