Re: Best carpet and adhesive to use on recarpeting my boat?
You'll have to shop around for the best carpet you like.
The best adhesive is contact cement, like the Dap Weldwood contact cement. It's tricky to use, but not too bad once you get the hang of it. Practice with scraps first and then do your small pieces first working your way up to the biggest piece last.
The water based outdoor carpet adhesive leaves a lot to be desired in my book. It weakens substantially when the carpet gets soaked, it will regain it's strength when the carpet and glue dry back out... but it's easy detach the carpet from the deck when it's wet. The solvent based contact cement retains it's strength wet or dry after it has been properly cured for 7 days.
