Some great information in here thank you very much to all who have posted
Great thread and lots to digest here so thanks for sharing. Always fancied having a bash at tweaking an old gun.

Hi all,
Has anybody used gt85 ptfe spray on the metal to metal parts?
Cheers J
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.

Some interesting tips and advice here, thanks very much !
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?
Any advice on TP sizes as I wanted to experiment with various lengths and calibre barrels

A simple spring gun they say
My Cometa 300 compact.22 has a TP of 4.00mm x 12mm
The .177 fusion has a TP 3.25 x 12
The 220 compact.22 TP 3.00 x12
All share bore size but strokes a little shorter on the 300-220
I want to fit a full length .25 barrel to the 220 and hopefully find a TP that allows a barrel change without any internal changes
I now see Cometa change their TP’s to suit what cal/barrel is being fitted
My 300 and 220 share the same bore, stroke and calibre.
The pistons are different and the 300 makes 10.8 and the 220 10.2, the 220 feels nicer to shoot and has become my go to gun, but at the range at 30yds both make the same 20p holes with 10 shots, the 300 definitely has a snap to it and feels lively compared, and I never thought it would be as accurate.
Ive now added a 7mm SS nose with a hwBritseal and dropped the power to 10 and it feels nicer in the shoulder. I can feel how much quicker the 300 is but another range visit to see if accuracy has changed is needed

I have been recommended red lithium grease to use instead of Molly.
Has anyone a view on this.
Many thanks
Really great thread, I've not taken a gun apart for nearly forty years. Great reading!

Its all about what to use where.
Moly paste is great for lubrication of metal-to-metal surfaces, like the rear skirt of pistons without synthetic bearings.
On synthetic spring guides, other lubes can be good, I prefer PTFE containing greases on tight guides.
Thicker tacky greases like I suspect your red lithium grease may be, can be used sparingly to reduce vibrations when guide-to-spring fit is sloppy.
Too many airguns!
