I tried to get some good photos of my sanding effort today. But the light doesn’t do it justice.
If you look close enough at the transom you can see the fairing has hardly been touched. It will need refilling. (the lowest spot on the boat) But 40cm further up glass is already showing ( a high spot) Then another low spot just before the centre board case. And then another high spot on the centre board.
It was a lot more sanding than I thought, but I got that much done in 1 ½ hours.
