Made my rocker look new again!

[This review was collected as part of a promotion.] This was so easy to use. It took very little of the gloss to cover the rocking chair. The odor was really strong and was strong for a few hours. The drying time was between 2 and 24 hours. The first couple hours it was sticky to the touch but was drying pretty fast. It was completely dry by the next evening. This seems to be very durable and will hold up.

Strong and beautiful finish

[This review was collected as part of a promotion.] This spar urethane is great for interior or exterior. It makes the project water and UV resistant. It brushes on very smooth and covers a lot of area. It does take some time to dry between coats but has a low oder. I used this can on taking some rough sawn red oak and turning it into a floating shelf and a bench for a laundry room make over. The finish is very durable, resistant to chemicals, and nearly scratch proof. My go to choice for long life top coats.

Great shine, quick drying!

[This review was collected as part of a promotion.] This spar urethane is the perfect finishing touch! It provides great coverage with very smooth application. It only took around 20 minutes to dry in the sunlight and provides a great shine. This is my go-to finisher for all my wood projects.
