I used the high gloss on my floors today. Floors in part of my house have not been refinished in May years and this product made them look absolutely beautiful, I am amazed. Floors that were refinished 13 years again, that do look quite good, needed a little something, they too look wonderful. This is an excellent product. The bottle did advice that you should test an area first, I did do that on my older floors to make sure this would be OK with the existing finish. Others reviewers must not have done that.
