I am redoing in the interior of my 78 BJ40 with an aqualu aluminum tub. I've been looking for a good way to form a vinyl floor to it as it's not the same as a factory tub. (so I can't just order a flooring kit as it wouldn't fit properly.) I was thinking about ordering sheet vinyl and moulding it with a heat gun, however I can't find where anyone has done that before. Will it work? Thoughts? Suggestions?
