Good primer and rattle can enamel, repeat as necessary.
My rock sliders have been hit on trees, dragged on rocks and stepped upon by kids and elders alike. No paint job will be permanent so I'd rather make it easy to repaint!
I can attest to their hardiness! I had landed my truck hard on these sliders multiple times and I regularly use the kickout to rotate my truck around obstacles on trails - they don't even have a slight dent on them!
Hell Naw! No to the meat rippers. My 5 and 7 year old boys continuously slip and get there leg lodged into the space between the two tubes. One of these days I will get a slightly recessed diamond plate welded on there to help with that.
