## Questions & Answers

**Q: Would anyone recommend this product for countertops and around sinks?**
A: No, this is a great product but remains a little flexible. You would want a 2 part Epoxy ( very easy to apply) or a poly based product. System Three has a great epoxy line or get a "bar top epoxy".

**Q: Will this  over previously stained sealed wood**
A: yes as long as you sand with 220 first

**Q: Does this work well on outdoor Acacia wood furniture?**
A: Depending on the wood..but generally I would say if it works on a boat..it should work on wood like a clear coat..

**Q: Being an oil-based varnish, I know this product will have an amber cast, but is it slight or moderate in color?**
A: slight but it will darken with age.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Marine Wood Finish
*by M***O on September 28, 2024*

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
*by J***E on August 20, 2023*

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
*by J***M on June 24, 2024*

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,
