jay, the dark blue that is shown...gonna assume that it was applied by a previous owner. Am sure the dark blue is tough on bare feet on a hot summer day.Is it paint with a nonskid additive, or is it dark blue gelcoat with cabosil? Or is it Rhinohide, or a similar coating? Based on the pic, looks to be Rhinohide, etc. Nice install, BTW.Depending on what it is...and that will be the determining first step...we'll go forward. Want a compatible material going back down without too much work for you.
You can sand the Tuff Coat with 80 grit and recoat with a different color Tuff Coat. John Dupree did his deck in Durabak - check out the thread: http://www.classicaquasport.com/phpbb3/ ... bak#p49802
