Mid-20th century Salesman Stimulator for hardware stores circa 1955. "Just TRY to remove them…"
PC-7 was (and IS) an epoxy mix that forms a bond which lasts! Affixed here is a golf ball, several pieces of plywood, a rubber stopper, a metal hook and a ceramic tile. All bond to a bottle of A-Treat soda bottle from Allentown, PA. Guess what? A-Treat is still being made too! They will celebrate their 100th Anniversary of thirst slaking in the Lehigh Valley of Pennsylvania in a year or two. I hate to sully their reputation, but Wikipedia already has! In 1991, the company was the subject of regional news coverage when a smear campaign was launched against A-Treat as it tried to sell its sodas in NY. The campaign, which targeted African-Americans, claimed certain brands of carbonated beverages — including those produced by A-Treat — were actually manufactured by the Ku Klux Klan and contained stimulants that would "sterilize the black man". What???????? That's crazy…I guess the bottom end of the soft drink market is brutal.
As for PC-7, the bonding material which appropriated (or co-branded?) A-Treat Bottles, they were founded in 1954 and the goop still works. This survivor of the retail hardware industry proves it still does, even after more than 50 years.
