Have a Space Maker Duster I need a little help.....

Thank You "Fishbreath, jdheval, Badsport, and Blackbomber" for all of your input. Your really not gonna believe this but I stopped and picked up a single blade scraper ($1.99) and had some stuff at the house I use on my camper to clean and get blackstreaks off of it. You can get it at your local "Dollar General". Its called "Awsome" costs about $2.00 for 1/2 gallon. It is water based and you can use it for about anything that needs to be cleaned. Well I sprayed it on the old slathered glue and let it set for about 3 or 4 minutes, then used the cheap scraper and the glue actually just rolled off (with a little bit of elbow grease).. I actually was kinda stunned.. But hey... if I get it down to metal or the old paint I don't have to anything but rinse it off, and put the new carpet back on. See below..
