Re: Underside Coating Preference
A lot of good ideas and products used here. My first go around with the fenders I have were coated with coal tar epoxy, which held up great over the 7 years since I patched them. I'm leaning towards doing epoxy coating again, but not as thick a product, then topping with an undercoating. But I'll see what else people have done
