I have used Semco exclusively on the windows, rails, swim platform and steps on Chateau de Mer since 1986. It is very easy to apply and very easy to maintain. The only issue (not for me) seems to be folks like to see shiny wood. We are happy with the non gloss effect. In all those years, we only stripped the Semco once, and that was by accident. The admiral wanted to do a 'deep cleaning' before adding the next coat and the full strength detergent cleaned it down to the wood. I guess this would be a good thing if you like to strip the finish once in a while. We use the Golden Tone color. No experience with other colors. Maintenance coats just require a wipe down with water before beginning. No sanding ever. Just a happy customer. No connections etc. YRMV. Bob
