I currently have TWP 205 California Cedar on my deck. It's 4 years old and stained originally with TWP 205 and 2 years later with same. I have read good reviews for both TWP and Ready Seal and would like any information from actual users.
TWP 200 is a better and longer lasting stain then Ready Seal. BTW, Ready Seal is not a "contractor grade" stain. It is a non-drying old based coating that fades fairly fast in our experience.
