System Three 1850S16 Clear Marine Spar Urethane Varnish Coating, 1 Quart Can

I have used this product for years at a marine varnish for my wooden kayaks. They are always sealed with fiberglass and epoxy/resin. Other reviews were talking about using it on doors. Not the appropriate product. It is a marine varnish intended to use on boats, kayaks, canoes, etc. Excellent product. I renew the varnish on my boats every 2-3 years. They are stored inside when not in use so less UV damage. One kayak has last 19 years and looks as good as new.

Made my kayak beautiful. I did have a bit of a problem finding the right thickness, the first coat I added thinner on a 1-10 ratio and this made it thin enough that running was a problem, so I didn’t add any thinner on the second coat and that coat went on too thick. Find the sweet spot and you’ll love this rod it.

Looks very nice. Went on well and dried fast. Only problem, I ordered gloss and got satin

Slow drying time but that is what makes it work so well to refinish and build up layers and layers.Picture of very old door that now shines with six coats of sanding and finishing. The attached photo shows how nice the very old door looks after finishing the build up of the 6 layers or coats.

Very easy to apply with a good brush. It is suggested that multiple coats may be required, but I only needed one.
