Bob, I tried various strippers, read the other posts from those who had gone before...in the end I used an Aircraft Stripper, the kind for metal not fiberglass, made by Permatech. The only place you can buy this is at a commercial paint store, one that sells auto paint. Brush it on, leave it for 2-6 hours, the longer the better. Using a razor knife to cut around cabinets (yes, the interior walls and cabinets were in place and taped off, all the windows and screen where off) pull the vinyl off the walls kinda slow like. I tried the application of plastic over the stripper but found it didn't make a real change in the workload or effectiveness of the stripper. It's labor for sure but O, how glad I am not to see the ugly almond walls with the lovely accents of blue and pink flowers (or was that slate and mauve?). After pulling off the vinyl in patches about 3x3' some stripper can be applied to the areas where the adhesive didn't come off completely. It looks a bit like a hatch pattern in the aluminum and isn't really that bad until you see an area where the aluminum is clean and free of all adhesives, then you see the work that is left to do. I found the removal of the excess adhesive to be the most burdensome. It required more stripper, more time, and then gentle scrapping with a Formica sample chip (they work great and don't mar the aluminum). Also, (very important) while scrapping the adhesive have a cloth saturated with Goof Off (the yellow micro-things from Costco) which you use to wipe and scrub, and rub and keep rubbing untill all trace of adhesive has dissolved. This does take time, but really it's the only thing that makes sense because if you like AS then you must like aluminum! Why did they do that to the walls in the first place , WHY???
I also stripped the painted screen frames with this powerful and toxic wonder-of-a paint remover. The aluminum frames on the aluminum walls...YUMMY!!
It's worth the effort. Good luck! Sharon
