Home Depot or Lowes or somewhere like that probably has the best price on 24oz. rubber backed, UV resistent outdoor carpet. Because by the time you order and pay freight on carpet from any supplier it gets too expensive. They have the 3M spray carpet adhesive also. I always recommend that people take their hatches off (usually pop riveted or screwed on) to re-carpet them to make sure you get it around the edges on all 4 sides. When putting them back on, use stainless screws, that way the next time you need to re-carpet you won't have to deal with rivets.
