Contacts are gold for sure so that makes me feel better. I love the simplicity of this mod it is great and pretty easy to work on it seems. I have noalax right now, will that be okay until I can get some deoxit gold? And should I apply it to where the contact makes contact with the battery?
Push down the firing button and apply some to the end where it touches the battery. You can also put a little on the top of the battery. It just takes a tiny bit! Using such low ohms you should clean off and re-apply every week. Sooner if you notice sparking or dropped performance.
