Rhino lining-for Rock sliders?

Hardest thing to keep clean….Rhino lining on Rock sliders!
I had a choice of ordering, bare metal , power coating or Rhino lining..I choose the Rhino coating..
I live in Hawaii and I do lots of fishing in the ocean beaches ,lots of salt in the air..
I also live on a coffee farm..mainly dirt roads on a hill…actually you need to use 4 wheel drive just to get home and back up the hill to the main highway ,I live off the grid too..

The coffee farm is at 1000 feet elevation and it rains a lot…my truck get muddy every time it rains, summer in Kona mountains , where I live, it rain almost everyday during this pass summer…. The Kona Coffee trees love high elevation, nightly rains and hot sunny days….Every tried real home grown KONA coffee! Be aware not every Kona coffee sold uses real Kona coffee beans…

Please consider NOT using Rhino lining on rock sliders….the dirt or mud,stains the sliders, looks a dirty brown, hard to keep it clean…either paint with a smooth paint or power coating?

I finally repainted the rock sliders with Rust-oleum engine paint ..Black…but the rhino lining is a rough texture…dirt and mud will fill in the pores, by the next rain…
