Easy to use, looks good

This stuff was being put on new acacia patio furniture that I dont want to weather to gray,and crack. It looks like skim milk in can. I put in cedar tint ( sold separately). I gave the furniture a very light sanding with extra fine paper, just to open the pores. It went on smoothly. It gets absorbed almost immediately. Gave it 2nd coat within 15 and was done. Looks great! Seals the furniture to keep it in good shape. Has satin look to finish. Nice color. Looks rich. Now well see how it holds up over time. Soap/water cleanup.

Excellent Stain and Sealer

This is one the best stain/sealers on the market. It goes on easy, clean up is easy, and lasts a long time. The color tint is excellent.
