I have a polo boat and the resin on the underside has flaked quite a bit. I've watched the composite kayak repair video and have a decent understanding of how to do patch repairs. But in this instance it looks like so much of the resin is flaking off that I need to sand off a lot (most) of the resin on the underside of the boat, so I'm wondering three things....
1. Which resin should I use (I've used the rapid repair/quick setting one before but looks like a slower hardening would be easier to work with when doing large areas ?)
2. Can I use release film on such large areas ? Or how best to get a smooth finish ?
3. Is one coat sufficient ?
tks!
