I want to add non-slip /anti-skid strips to the fenders on my trailer. I step on the fenders as I step into the boat. This is a double wheel trailer. The fenders are thick, strong metal that can easily hold my weight. I can find anti-skid tape strips at the hardware store. (see pictures) These are 6 in. by 30 in. and would fit very well. They are not made specifically for boats. Should I just try them, or are there better options out there?
