Father-Son 1974 Duster Project

I bought some brush on bed liner to recoat the floor of my trunk. This is where I did some of my ugliest fluxcore welding, grinding and seam filling in this trunk when I was still learning to weld way back in the beginning of the project. Initially I used the rattle can Rustoleum bed liner. It looks nice but I was looking for a thicker coating. I brushed it on and I think it will do the trick. It can even be painted in the body color. Wondering if inshould do that?
Lots of fumes in the house and my wife is on the war path...
