Personally I wouldn't get the noalox. I'd get some deoxit gold.

If you sub ohm fairly low, I would get the larger size. If you are around 1 ohm or above the 2 ml tube will last a long time. I use one drop on my finger for my grands. You'd use a lil more than that on maybe on the P67 to get it between the + contact and the striker plate. As to the rest I'll let someone else advise.
Thank you, that's very useful information. I checked and a local electronics store carries that stuff so I'll pick some up.
