Hi there! Wurth do a lubricant called HHS 2000,It is excellent. When you spray it,its very thin(like WD40)but as the thinners/solvent evapourates,it thickens up.It has a very high pressure rating so it doesn't dissolve or wear out/off easily. Wipes off with any alcohol based solvent,wo'nt affect any internals and lasts for ages. Use it in lock barrels at work all the time!
