TBH I'd just spray a liner in it, drop in the bed mat and leave it. Not like that much of the pumkin comes through.
That was another thought that I had. For now they will get primered at the minimum and bedmat cut to fit around tubs and leave it like that till the luv is back up and going. Then ill look I to a bed liner.
I don't know how much comes out, but i would get the GM badge cut and tack in over top of it and the line-x it.
That would look cool, but I throw too much stuff in my bed to have anything nice looking on the floor.
