Here's a picture of my PrecisePlus 18500 with a 306dca Twitter Special I scored last Friday night. Looks pretty good, except I'm mulling the advisability of dulling down the finish. I dunno, I can see myself really ruining it.
The 306dca is a weird little contraption - not sure what it really does besides allow me to use my fantastic Super-T tip with a 306. I know it stops leaks, but I've also found I can flood it. It also delivers a much cooler vape than your typical 306 setup would. I've only had it for about an hour or so so I'm surely a noob.

Awesome pics Wingapo! Hey wing, maybe you already answered this, but where are the hills/mtns you took the 5th pic from the bottom? Really beautiful there....

I couldn't tell you the exact names of each mountain but they are part of the Sangre de Christos Mountains just behind the house on the way to Las Vegas New Mexico. I love my backyard and my office! Dragging myself out of the hammock to go to work is so hard to do every morning.

Love the mod, David!
I'm getting a little more used to the 306dca and what it can do. But I'm experiencing something weird with it. At this point I'm not really sure if it's just my imagination, so I won't elaborate until I'm sure. In the meantime since you have experience in metallurgy, do you know of any particular reactions between rhodium/stainless steel (and any other components of the P+ atty connection) and aluminum in the presence of electricity and/or heat?

I know that the Precise +'s will kick a new atty's behind.
Yes it does. Kicks an OLD atty's behind. It just kicks.
Oh, I'll just say it out loud.
The 306dca is made out of aluminum, including the threads. It seems that almost instantly upon firing the threads on it and the threads on the P+ atty connection develop a black powdery "tarnish". Comes right off with a quick wipe. Now I know that threads in general will get grimy/sooty over time but I have never noticed it happening so quickly. Juice is not a factor because the 306dca is a sealed unit.

I'm going to pay a little attention to this for awhile.

Aluminum is a poor material choice to use in the atomizer connection as Aluminum is an extremely fast oxidizer. I'd suspect your DCA aluminum connection is oxidizing and creating excessive resistance and heat, and the black is powdered heated oxidized aluminum sloughing off.

It sounds like this new delivery system of power is just too much for those aluminum threads to handle ;) That is pretty crazy though, I have not noticed anything black on my threads, I am not using a dca but several different attys and cartos, the only thing I have had to wipe off is excess juice and thats only cuz I dont want my cafe latte to mix with my gummi worms :)

Do you think it will slow down at all or will it just continue?

I tested the resistance of the DCA/306 and found that the reading had not changed from the reading of the 306 alone, 1.5. But I think your assessment is correct, it's oxidized aluminum.

The creator of the DCA states that aluminum is used on purpose for this application. Since it's such a stout little piece of metal he thinks it's better to have the unit be semi-disposable - it's better to sacrifice the threads on the DCA in a dropping accident than the threads of an expensive mod.

It's interesting that this oxidation seems to only occur at the connection between the DCA and my P+ and does not seem to occur at the interior connection with the DCA and 306. That's good! You don't have to worry about inhaling anything that's going on at the battery connection because of the sealed nature of the device.

Have you tried performing a loaded voltage test? Can you tell if it hits harder with the atomizer just screwed into the unit vs screwed into the DCA? I think you mentioned you felt a little cooler vaper with the DCA on? Also, does the interior (306 to dca connection) perhaps get any juice residue on it?
