High gloss

Would Recommend

Best stuff for outdoor or indoor use. Will never peel. My treated wood projects are still outside after six years and still look like new. Usually use eight coats.

[This review was collected as part of a promotion.] In retirement I do a lot of woodworking crafts. In particular canes and walking sticks. And I finish all projects with the title product. Easy application and a durable attractive finish. Highly recommended!

Good gloss finish

The gloss has a good finish. On surfaces outside it last about 2 years, depending on weather and exposure to sunlight.
