    I've used it on several pieces of machinery and the results have been very disappointing indeed. It works well as a penetrating oil, but is pretty useless as a lubricant and hopeless for rust protection.

    I use a lot of GT85 - on the various motor/pushbikes/garden tools. Prefer it to WD40, in fact. Fine for gears/chains, show no signs of rust/seizing, kept outside all year round. The garden tools get a heavy coat over winter. But have only ever used it to soak a seized piston on my guns. Think it's too thin/not durable for gun use.

    Here's a great test of various lubes and their rust protection results.

    What’s everyone using these days instead of the dri slide? I’ve seen “Phillips Molybdenum gun lubricant” for sale , has anybody had any luck with that or any other suggestions ?
    Or should I just apply the moly grease as thi as possible to the inside of the chamber?

    Depends on the gun. The 25mm piston 77’s seemed to benefit from opening to 3.9mm, modern LGU/LGV were similar. How much air are you shifting and what is the current volume of the TP?
