I'm a big fan of the Lucas Oil Products. Almost all I use. The Extreme Duty Oil is really good on most firearms. I find their aerosol CLP works the best on the rimfires.
I'll use the Hornady One Shot when going into a dirty or dusty environment on Bolt Guns, or on ARs with NiB or QPQ bolts.
Their bore solvent should be renamed to "Choke Tube and Ultrasonic Cleaner". It does not do a good job cleaning bores, especially copper, for which I go to Montana Extreme or GunSlick foaming.
The only product they have I have seen degrade and separate is the grease. Leave it for 4 or 5 months and there will be a stickier dark blue grease and lighter blond oil. So that is a product I only use before a match on my Shotgun action.
