We didn't do an exploratory grind deeper than the shots I posted. It's clear that the hull
needs to be peeled. I can't get a moisture meter in Turkey
where I am, and we can't treat the hull
this year. I'm currently sealing up the hull again, but today, I've dropped the rudder
off. There's no gel coat on the rudder
, and the osmosis
is different to the hull, the pits are wider and deeper, and there's evidence of hydrolysis, some of the glass fibers are white, leading away from the pits. I take that to be resin decay from water
migrating along the fibers.
I've found a local guy who will just peel the rudder back to solid glass. I'm hoping I can borrow a moisture meter to determine how deep we have to go. We can dry the rudder indoors with fans and heaters, but can only afford a few days drying. I know it may need longer, bit I couldn't leave it as it was. I'll probably give it two layers of glass and epoxy
resin, then barrier coat it.
Thanks for the great video on the gel plane. I will look to buying
one, probably in the UK. Then I need to find a cheap
hard stand, somewhere warm, where we want to spend a summer, and have at the whole hull.
Thanks again for the excellent advice.
