I gave up on the carpet in my 1993 16 ft Lowe . Every panel and hatch had to be removed to get the carpet off since the carpet went over the edges and onto the back of the panels a few inches . Removal of the carpet adhesive was a little bit more of a challenge than I expected . I used Raptor Liner truck bed liner in light grey and applied with a cheap Harbor freight drywall hopper gun with the small nozzle at 80 psi and about 3 ft spray distance . I had to give it 3 coats of the liner because if you get it to thick it tries to run and sag before it gets a chance to firm up . Repairing a sag was easy , just went over it with a DA sander with 80 grit to smooth it out and remove the bulge it made and the next coat hides it like it was never there . Its not the smooth splatter look but more of a 40 grit sand paper look .
I know its not for everyone but for a minimal investment I made a inexpensive boat look a little better than it did with rotting carpet .
I did end up pulling the side console back out and removed the texture . I didn't like the look of every surface being textured .
Light grey gets to hot in the sun for me so I then painted over the texture with Seattle grey polyurathane and couldn't be happier .
