Marine Wood Finish
I used this product to protect wood plant shelves on a patio. This produce has protected the wood from outdoor elements. Great product. Easy to apply and clean up.

Used on kayak
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.

Absolute best spar varnish for wood boats
I just sanded and reapplied to my wood kayak for only the second time in ten years! Excellent UV protection out in water and takes years to lose its shine,

Shine that lasts
This product is excellent. It is UV rated and goes on great with a spaygun or brush. Put it on my wood boat 3 years ago and it still looks bright.

doesn't hold up in the sun
I had high hopes, it looked great but within weeks the sun started burning it off. I followed the instructions and used penetrating epoxy as recommended. Now I have to use Cetol which holds up in the sun but has this orange color
