I only know that my owners manual for a YHM ULT Titanium states that using any kind liquid voids the warrantee. Not going to take that chance on a $800+ can.Depending on the type of suppressor, the right liquid can help with cooling and sound reduction. I run my suppressed shotgun very wet using a mix of one part water soluble cutting oil to ten parts tap water. The water eventually evaporates, leaving a thin film of oil which helps to reduce corrosion. Jack.
