I got two Vortek PG4 kits in my mailbox today (HW30 'HO', HW50 'SHO') and both came with red grease that looks like the Lucas Red & Tacky I use on my Kubota tractor. I know the Lucas R&T is great stuff and I pondered using it on my airguns. I have tentatively decided to use the moly I got from PA as the primary lube for installation of the kits (following a thorough cleaning of the factory grease and some de-burring) in my new HW's.
Saw a detailed Tuning Kit installation video on YouTube (in German) where the kit included a nifty piece of clear sheet plastic which is rolled into a tube & inserted into the receiver; the piston/seal assembly is then inserted into the plastic tube to prevent any injury to the seal during re-assembly. I like that idea & plan to do the same during my kit installation, was wondering if any AGN kit installers have tried that procedure themselves.
My Vortek kits are still unopened so I haven't seen the instruction sheet yet.
