Yes:
I saw Sniper's Hide posts about this from 2013. There are a couple where the Wipeout owner claimed at first that the red color guys were getting out of their barrels was due to the red colored caps of the can leaching into the product. Then there was a post of a custom gunsmith having 5-6 barrels ruined like mine. That gunsmith got no help from Wipeout.
Owner of Wipeout on the phone told me I was the first to have a problem with his products. I reminded him of the Snipers Hide accounts. His reply to that was, "Well, what are you wanting from me? Are you just trying to win the lottery?"
