Re: Marine Carpet
I installed Durabak (a hard rubberized coating similar to bedliner) and I have mixed feelings about it. I put down two layers of textured Durabak and one layer of smooth over the top, and it is very comfortable to stand on and it's not too slippery. I don't like how it catches and holds dirt, though. We do a lot of river boating, and the sand/muck that gets tracked in when we beach is not easy to wash out. The fine silty stuff from the river actually seems to stain the Durabak, although it just might need to be really scrubbed hard. (Carpeting, of course, would be even worse in this respect.)
What I really don't like is how it's wearing. In a couple of places (on the pedestal seat bases that are part of the decking; imagine pyarmids with the top 4/5 chopped off), the Duraback is wearing off the corners. Also, I put down a rubber mat at the driver's station, the sort of mat you might use in a kitchen to relieve foot and leg fatigue. The rubber mat actually fused to the Durabak and, when I pulled up the mat, some of the Durabak was pulled off the decking. The mat wasn't used until months after the Durabak was applied and cured, so it wasn't a matter of just being stuck in wet Durabak.
I'm now needing - at a minimum - to repair the Durabak where it's worn away and where it pulled up with the rubber mat. I also probably need to buy some more of the smooth Durabak and coat the deck again, to see if I can get something that isn't so hard to clean (and yet is still non-skid).
I don't dislike the Durabak, but if I had to do it over right now, I'd go with gelcoating the deck and then applying snap-in carpet or using something like SeaDek.
I think Durabak and other bedliner-type applications are pretty similar, so I hope this is useful information.
