Good replys guys the photo shows you dont put much non slip on at all . Ive repaired the decks on two cats this year and had to remove that stuck on non slip, the mess I found under it and the effort required to clean it up, orange oil, thinners, acetone,elbow grease, scrapers days and days Ive sworn of stick on for life which is why I'm going to paint on. True to my way of doing things I may have been going too far, perhaps I'll just paint a bit of non slip on then see where else I need it.
regards
