OK all I just wanted to post because it may be helpful. I have been doing my research for a couple of months now and finally started the replacement of the carpet in my 99 triton. So when it came time to remove the old glue I decided to try oven cleaner. I did not see this recommended anywhere but we used this for glue removal in the body shop all the time and used it to remove the glue from some stripes on another boat. Well on the areas with the backing not stuck with the glue this really worked well. I sprayed it down scraped the bad areas some then used a scotch Brite pad and some soap and water and it was done. I had the whole boat and floor done in a couple hours not the hatches but all the fiberglass and gas tank cover. Best part it was much cheaper then most other stuff people said to use so I am glad I gave this a shot first. Not sure if the results will be the same with all glues but but those doing this job may want to give it a try. Plus it will not hurt your gel coat.
