Right,.

I left it overnight to dry. Felt less tacky.

Rebuilt it just now and it's running nicely. Only had about 15 shots through it but cocks really nicely. Had to call it a day over the chrono as the boss came home.

Hopefully at the weekend I can run it in and the shots will settle down and run more consistently. Approx 7 fps spread between shots, so quite pleased.

For anybody interested, it raised the fps by approx 10-20fps.

I built it up in 2_3 coats, dried over night and left most of it on the piston. I gave the cylinder a very light dust to remove the excess but didn't buff it so to speak. Left a small trace of dri slide on the piston seal.. Put a smidge of moly grease on the rear of the piston skirt. Pushed the piston up and down the cylinder and twisted it to bed it in before I put the spring back (not sure if it does anything by for peace of mind more than anything)

Hope this dri slide runs nicely for a while now- fed up with rebuilding it!
