That's Selley's Kneed It for metal. Very tough stuff. What happens there is bar oil leaks out coz it corrodes through to the tank. I grind it down maybe 1mm, clean it with acetone, and load it up with the Kneed It stuff like a dentist doing a filling.

Let it harden 2 days then carefully grind it down so everything fits in. Bloody good stuff and as you can see it holds, doesn't allow corrosion. But it's very hard to do it everywhere due to the thickness of it.

I also sand blasted a new saw and tried both epoxy and fibreglass. Took ages to file/touch up/grind bits and pieces to assemble the saw due to the thickness of the coating. Crap, they were blistered off and gone within 2 weeks on the surfaces that really cop it. Also where some did remain it just corroded beneath it.

So stuff it, just buy a new saw every year.
