Cylinder gasket and/or sealer for 025?

[yawning_dog]

Hi everyone. Sorry if this has been covered before, but I couldn't find a specific answer. I'm replacing the cylinder in an 025 and I'm trying to figure out if there's supposed to be a gasket between the top and bottom of the cylinder. I got a used cylinder as the replacement and there's just some rubbery red stuff there now. I suspect it's some sort of silicone? Anyway, does anyone know what's supposed to be used? And assuming there's no actual paper gasket, do you smear gasket goo all around the perimeter of the cylinder, including over the bearings, or just on the cylinder mating surfaces? Thanks for any info!

I use Permatex- Anaerobic gasket maker,
I put a thin coat of it on the cylinder base, then push gently while rotating side to side slightly, install bolts with light torque, wait about ten minutes and tighten.

Dirko HT sealant

is the stihl oem, however the one that Manual reccomended is also very good
