Tarp and Dock rash on my boat.

This was caused when the tarp ripped on the way home from Texas, and the soot from the diesel engine entered and etched the varnish.

The same side, starboard, same problem.

While loading my boat at Texas, a dock hand let it get away and it smacked the concrete wall.

A little sanding with a sanding sponge, and a coat of varnish, and all is well.
