Since there seems to be such a multitude of threads consisting of lube questions (like "what lube do I use?," "Is X lube ok?" and "I've already lubed something with an unknow lube, will it be ok?") appearing lately, I decided to crate a FAQ.
1. What do I use to lubricate my bushmaster?
The answer isn't necessarily a simple one, and It's dependant on many things. Some commonly used lubes are Dow 33, Dow 55, Slick Honey, Evil Pus (Basically Dow 33), and Shocker Lube (Dow 33.) These all have different properties and are good for certain applications. Many people advise against Dow 33 because of the quality, and recommend Slick Honey. Many people, such as myself, find the various forms of Dow 33 to be fine. Slick Honey is higher quality, but may damage O-rings, thus you will find yourself replacing them more often. Finally, Dow 55 is similar to dow 33, the only difference is that Dow 55 swells o-rings, making for a tighter fit and/or seal.
Verdict: If you aren't sure, Just pick up some Dow 33/ Shocker Lube/ Evil Pus. No matter what you do, DO NOT
use any oil-based lubricant. It will eventually make it's way into the solenoid, which will mean an $80 investment for you.

2. What do I need to lube?
On a bushmaster, the following parts need lube:
- Ram O-rings
- Valve O-Rings
- Valve Cupseal
- HPR plunger (piston)
- LPR plunger O-rings
When applying Lubricant, rub a light coating on the outside of orings, and wipe away any excess lube. I.E., you don't want "globs," but you don't want to be incredibly skimpy. Keep in mind while lubricating that one package of lube SHOULD (unless it's very small) last you a good long time, and you should be lubing your gun once roughly every 10-12 cases of paint.
3. Does my bolt need to be lubed?
The short answer is No. However, you may want to, and many people do. The problem is that you can NOT use any of the previously mentioned lubricants. Stock and aftermarket bolts are made from Delrin, a high-durability, low-friction polymer material similar to hard plastic, which will swell if any of the aforementioned lubricants are used on it. Bolt swelling means that it won't fit as well, or if large amounts of lube are applied, wont fit at all. When lubing the bolt, use a product called tri-flow. It won't swell the bolt, and will greatly reduce friction on your bolt. Tri-flow can be bought here: http://www.paintballer187.com/misc.html#lube
When applying tri-flow, use about three drops on your bolt and then rub it around to cover the entire surface.
4. Can I use X lube for my bushmaster?
General good practice is to NOT use a lubricant you are unfamiliar with without first checking on these forums. However, with the lubes mentioned above being so common and relatively easy to find, you shouldn't need to resort to an obscure or unknown lubricant. If you must, though, post and ask first. It'll save you time and money in the long run.
Well, I hope this helps people, and I hope it decreases the number of lubrication threads here. If anyone thinks something should be added, PM me, and I'll add it if necessary.
