Last night we kept the windows open in the house. Which means... fall is around the corner. I probably have a couple of months of paddling left without a dry suit.
So my thoughts have turned to taking care of the scuff marks on the boat this winter and other maintenance. Those didn't take long. Good thing I obsessed about every scuff before I varnished.

Also, I didn't put quite as many varnish coats on as I wanted so I would get some days on the water.
1. I've heard not to reuse varnish, but I have some left over that arrived in June. As long as I strain it is there a problem using it?
2. The keel line has several layers of glass. Does anyone put anything else on it? Obviously a bunch of scuff marks there.
3. I finally received graphics I ordered for my stern that would go on the hull, right about the waterline. How would I do this? Do I need to remove all the varnish in that area first? Too much of a pain?
4. My deck lines should be good, but I will inspect them for any frays. I looked at what Chesepeak Boats does with their boats. Any other suggestions?
Thanks.
