Tank, i too went on an endless search for Blue Tak not long ago and came up empty handed. Elmers's tak will work just fine, mine was orange, found at a local grocery store!!LOL also, you can find Poster Putty at Walmart in the school section. i use it for tight demarcation lines on some camo jobs......works great!! my wife buys future floor polish at a chain store in our area called Dollar General, i'm not sure if they're nation wide or not, but Walmart will carry it also, on the cleaning isle. later.
