I've got a utility trailer with an expanded steel mesh gate/ramp on it. It's fine when dry but the gate becomes really slippery when it gets wet. Does anyone have any suggestions for a non-slip costing I could apply to it? I have considered Linex but the dealer who did my truck said they only have what I got in the track bed. Might be good but I would like something more aggressive. Plus it's $6.50 a square ft.
