Thompson's WaterSeal 3.78-L Clear Low VOC Oil Base Wood Waterproofer and Protector is rated 4.4 out of 5 by 7.
Rated 2 out of 5 by from Not that great I put it on a month ago, some areas look good, others don’t. Knots in the wood look funky. It’s dry, rained a bunch of times but my feet are itchy when I walk on it and have to come inside to wash them. Stains bottoms of white socks. Leaves bare feet marks or bottom of shoe imprints on tiles.

Rated 5 out of 5 by from So far, so good! I built a cedar skirt around my house in the fall. It looked very good, but I wanted 2 seal it, so it won't turn grey. Have had a very busy summer, but got 2/3rds of the job done on the wknd. It looks even better than before. The wood colour is more vibrant, the knots jump out. Very pleased. As long as the sealer holds up well, I couldn't be more pleased. Rick
