Many years ago I built a walkway (PT wood of course) from my parking area to my cabin thru the woods. As the cabin is in the Adirondacks it has shown some aging from the extreme winters and gets pretty slick when it rains. I'm thinking of cleaning with a pressure washer but would like to treat it in some way to make it less of a slipping hazard when wet. Any suggestions? I did pickup (3) 5 gallon pails of Restore from habitat for 40 bucks but am reluctant to use that as I've read all of the horror stories about those products.
