I just recarpeted my 18' Ranger with 20oz. basscat carpet and weldwood original contact cement. I paid about $150. for 20' of carpet and the contact cement runs about $15. I needed about 3 cans of cement because your using alot on both surfaces. Do it yourself if you can handle tedious work. Alot of time to take the old carpet off scrape off the old glue. Try to keep the deck and floor pieces in tack you'll need them for a template. Well worth the time and I'm sure you'll save a ton of cash doing it yourself....
