Building New Shed and Want to Coat Floor to Protect It

building a new wood 8x12 utility shed to store my lawn & yard tools. will be a basic 2x4 stick structure, t111 walls, 2x4 floor with tongue & groove plywood floor. I want to coat the floor and lower portion of the walls (maybe 6-12 inches up the walls) to protect it from moisture, fuel, oil, etc... as this shed will house my riding lawn mower, push mower, trimmer, etc. Main goal is to help protect the floor if i can and make it last. I was looking at using the Bed Liner, as it seems one gallon should get me close to 2 coats. also the bedliner will give some traction/ texture to the floor as well ? or do you recommend another product for this purpose?

i have used several of your other products and have been very happy with them.
