I have a new-to-me Compac 19. The previous owner had tightened down the spreader sockets on the mast too tight. His work left this dimple:
What I've done is taped off the dimple and filled it with JB Weld. I'm now sanding the JB Weld so it is fair with the adjacent surfaces. The sanding has abraded the aluminum in a spot or two. Do I need to coat the aluminum in these places with some product to protect the mast from weathering/corrosion?
Thanks for your help.
