Contacted abbey concerning their sm50 gunlube. Asked if it was ok to use on the slideing action on my skan r32. Said i was concerned as it was molybdenised silicone oil and was worried it might cause wear due to the silicon oil present. His email reply was. " i have a bottle of sm50 on the desk infront of me and it does not say silicon oil at all. Abbey sm50 has never contained silicon oil and never will" then i sent a picture of the label saying "molybdenised silicon oil" back to him. Granted this bottle is 10yrs plus years old but the "never has"quote just made me have to send the pic of the bottle label to him. Still awaiting a reply
