Get online and go the the POR15Store.com and get a kit with Marine Clean, Metal Ready, and a quart of POR15 in your choice of color. It will come with instructions which will lead you to an indestructable tub finish. I also recommend that you buy a couple of their cheap paint brushes for application and a good pair of gloves to keep it off your hands, or you will be wearing POR15 until your skin wears away in a couple of weeks. /ubbthreads/images/graemlins/crazyeyes.gif
I also got a foil lined insulatin pad via Ebay from some place in Texas that sells it by the roll at a decent price. Applied the padding and the carpet with 3M Interior Trim Adhesive in a spray can for a real neat, cool job.
Good luck /ubbthreads/images/graemlins/cheers.gif
