Hi all, Just got a new van (new to me anyway). Ply lined on the sides, but nothing on the floor (bought van of my pal, he took up ply floor as it was all rotten anyway). Here's my question- Is it best to protectakote the metal van bed- OR- should I ply line then paint over that?? I'm thinking just protectakote the floor pan and this should be fine- there'd be no point to the ply would there? Anyone done this? Thanks.
