I wish I hadn't.
This product was recommended over what I've used without problem for decades, so I tried it. The color is awful and it dries sticky with no easy way to correct the finish or remove the product. I would rate it zero stars, but Amazon requires 1 star to submit a rating, so...

Great product- easy application
Expensive? Yes! Gorgeous finish? Easy application? Lovely color? Yes. Yes. And yes! My dock is cedar- this product gives you a “ChrisCraft” finish.

An excellent wood sealer and waterproofer!
I am returning to leave this review having 3 years of experience with this product. I purchased Seal-Once Marine Penetrating Wood Sealer (clear) in June 2023, 3 years ago, and applied it to a large gazebo (from Costco) on my deck. Seal-Once has done a phenomenal job of protecting the wood, and the gazebo still looks almost new. My experience with prior brands of sealer/waterproofing caused me to do a lot of research while selecting which protection to use on my new gazebo. I live in sunny California so sun damage was my primary concern, but we average 54” of rain annually so I was also looking for water protection too. I have been pleasantly surprised that this product has really surpassed my expectations. I am a very satisfied customer and will continue to use Seal-Once Marine Penetrating Wood Sealer. (The attached photo was taken right after the gazebo was first installed.)

Seems to look really great on Redwood nice natural look and feel
Works really well you have to Shake It Up first it looks like thin milk it goes on nice and smooth then you put another coat on within about 20 minutes it's supposed to last for a long time. It definitely s the water up
