I use Froglube paste on my Rohrbaugh. I like that it is very rust preventing, and that by being dry, it doesn't collect pocket particulate. I have read some reviews of it not doing well after being stored for long periods, but I usually disassemble, clean, and reapply once a month.
I disassemble the gun, wipe everything down with a cotton cloth an q-tips, and then heat everything up with a hair dryer. Then cover all the metal surfaces, inside and out, with the Froglube. It melts like wax when applied to a hot surface. I then let the parts cool off, wipe off the excess, and reassemble.
Froglube makes cleaning after shooting easier, too. It seems to keep the burnt powder from sticking.
It also shines the outside of the gun nicely.
Also, it is non toxic, smells like mint, and doesn't bother my skin.
Did I say I like it?
