So I just got a set of the G1 KO Single Carded Constructicons. First I have to say the quality of these overall are AMAZING!!!! Best KOs Ive ever seen. For those interested, shoot fellow TFW2005 member Deceptigtar a PM if you too want a set. Great guy, awesome product and prices and super reliable. I was lucky enough to get mine all shipped not attached to cards so everything stayed MINT!!! Now I want to know what everyone here uses to adhere bubbles to cardbacks. I want something that will last, hold strong, not fog up the bubble and dry clear. Suggestions?? Please only if you have done this for you own items as I only get 1 shot at this and DONT want to screw it up. Please help!!
