Short and descriptive is the best

This is an excellent product. I put it on 3 - 8' x 2' x 4' raised garden beds for some flowers. It dries quickly but leaving overnight is better. I used this size and it took care of project. The garden beds were previously covered with polyurethane but just for reinforcing the exciting coverage this is why I did another coat. We also live at a higher altitude, and weather changes quickly. Preparation is always key.

Water Based Spar Urethane Gets A Thumbs Up

This is the water based urethane finish I'm using on the wood refurbish on my boat. I bought a can of the oil based urethane just to compare the two and I like the water based urethane much better. Very little fumes, fast drying time so additional coats can be applied and mere minutes for cleanup of brushes with warm water
