Patching damaged tarp-like material under coach over tires
It looks like one of my rear tires threw up a piece of debris which smacked a quarter sized chunk out of the underside of the plywood floor above it.
Under the coach it looks like the plywood is protected by some kind of tarp-like material. It's a plasticy woven fabric that is up against the plywood. The debris penetrated this and took about a quarter sized chunk out of the bottom layer of plywood.
What would be the best way to patch up this damage? It seems like with rain water being sprayed up against the now-bare and damaged plywood spot it's starting to soften and rot around it so I want to get it properly covered.
Anyone know what the fabric material actually is?
