Today, I built and installed my new trailer gate extension. (will post pics nex week). I found something at Home Depot that may help others, I used it. I is an antislip additive, to paint. It is made by rust-oleum. It works great. ALL you do is mix one container of this stuff to one gallon of paint. It costs around 3 dollars. It is called RUST-OLEUM ANTI-SLIP. Found in the paint section. For me in the isle with the big five gallon paint containers. Try it on your trailer deck or gate, it does work.
