Comments about Pettit Z-Spar Z Spar Captain's Varnish Ultra Clear 2067:
I used this product on a wood strip kayak. I wanted a more clear finish that was relatively easy to apply. This is my fifth boat to finish, so I am not a beginner. First this is NOT a clear finish (I really am confused about how that name applies to this finish). It is as amber as any other varnish with UV protection on the market. A major disappointment for me.
Secondly, I had great difficulty applying the finish. I was working in a heated (70F) shop. It is a high gloss IF not thinned. I could not brush out the un-thinned varnish enough to get prevent sagging. When I thinned (with T-10 Brushing thinner), the finish would not flow to cover brush marks. Even after 5 coats (over a fiberglass/epoxy) the finish is dull and continues to show brush marks.
