Nobody likes having to sit out of the game, working on your paintball marker, clearing barrel breaks or jams. Keeping your gun clean and your o-rings lubed is not a ton of fun, but needs to be done every few weeks or about every 4-5 uses to prevent this from happening.
There are between 6 to over a dozen o-rings on a paintball gun, depending on your model. It is essential to properly maintain your marker. If the o-rings get dried out, they will crack. If you use the wrong oil or lube on the o-rings, it can damage them. The chemicals in certain lubes like Rem oil, can make them mushy and you'll end up replacing them sooner than necessary.
For this post, the topic is how FrogLube can be used for paintball guns. Designed to clean, lube, and protect regular firearms, because of the ingredients used in FrogLube, it not only CAN be used on paintball guns, it is a preferred lubricant because of it's preservative properties. Check out this FAQ from FrogLube:
Q: Can FrogLube be used with airsoft and paintball guns?
A: Since FrogLube is non-corrosive to plastics and rubber, it is the preferred lubricant and preservative for o-rings, non-ferrous and rubber parts. FrogLube will actually condition o-rings and improve compressed air and pressure tank retention properties.
Because FrogLube is not made using any chemicals, not only will it not hurt your o-rings, but is known to preserve materials like wood, plastic, nylon, rubber, etc on regular firearms.
Because FrogLube repels particles, I would also advise that you use it inside your barrel as well to lubricate it and prevent paint from sticking to the inside of the barrel, which in turn will help prevent barrel breaks.

There's a ton of information out there to learn how to maintain your paintball gun if you don't already know how. Do a google search to find detailed videos showing you how to take apart and clean your specific brand/model of paintball gun.
FrogLube is designed to prevent rust. I would recommend using it on the metal parts of your paintball gun as well.
