looking to touch up my trailer, one thing I need to do is replace the non slip material that is on the trailer steps around the fenders to climb in the boat. Not sure if I want to go back to the original material (skateboard type material) as it doesnt seem to last long. Do I need to be concearned with moisture gettting under what ever I decide to use? Also thinking about brushing on the bed liner stuff like hercules as a replacement
