Solutions to bad repairs

The boat got some pretty nasty treatment today. Yesterday I found out that the hook-loop/velcro sanding disks don't work all that well under heavy usage, and that a scraping tool and elbow grease work well, but it's tedious and hard on the hands to get through a millimeter of whatever resin was used and whatever fabric was used. So I was looking for some solutions that would work better.

Paint stripping wheel on an angle grinder. (I can hear people shudder.) It's very rough, but it cuts through the gunk on the boat quite quickly. One needs to be very judicious with pressure on the hull, because even a moment of cutting after the resin is out of the way will eat right through the wood. Fortunately I was able to get almost all of the cloth and resin off, exposing the wood in places, but not gouging. The more careful removal of the un-reinforced finish comes next - Will try some furniture stripper first, and see what that does..

Sanding off the white primer from the inside bits of the boat is also going to be a chore. Why anyone would put that crap on a wooden boat is beyond me, but...

That was another (approximately) 100 minutes of work on the boat today. Cleaning the resin and fabric off a section of hull about 1.5 m long (between the foot-stretchers and the start of the splash-vee) provided about 1 litre of dust and shavings.

Til the next time. Must take the camera to the boatshed one of these times....
