Mine is semi-shiny too. I have been thinking about maybe doing the truck bedliner spray. Tougher and more traction. Was thinking that just for the last one after slipping on it while tying down the Christmas tree this past year! Just not sure how it would look.

 

$90 at Atlantic British is the one I bought last year. I use black skid tape on the top of the ladder steps and on the top of my tree bars/nerf bars on my sliders at my door entrances. It seems to work well, and some of the guys I ride with use it as well, and no complaints. Just make sure the surface is clear and dry. Cut to fit on the ladder rungs.

I picked up this kit from HF. Think it was about $10 with a coupon.

45 Piece Threaded Insert Riveter Kit

Placed the ladder, marked the holes, drilled, put a thin coat of silicone around the inserts before installing.

 

I used the same HF rivnut kit, and 1/4" ss machine screws
