After the failed coating is removed, a good exterior paint will give the most protection, that is after proper prep and priming.

If it is wood and not painted you can use CWF clear. Just reapply every couple of years. I love that stuff!~

That's a great idea Kelly for keeping the natural look.

Yes, I prefer the natural wood. :) CWF goes on rather thick and it's what I use for my outdoor projects. It goes on kind of orange but dries very clear and really protects the wood. Just make sure you get CLEAR CWF. I even use it on my log and slab tables etc that I built to leave outside. :)
