Hi guys. I'm Russ
Firstly, thank you all for being part of this community and the wealth of info you've all contributed to!
I've been reading FC for a while, I FC'd a few months ago, and I even got to try an OG! Now I'd love to get one that'll last, so I'm working on a Ti (something) S order.
My eye is definitely on a Damascus steal mid-section. I understand I would need to maintain it a bit, which is fine. Can you guys with a steel bod chime in on your experience. How often do you treat it? How's it holding up, etc.
I understand the steel is not in the vapor path, but is in the intake path. I'd like this thing to be solid and last for ages, and am slightly concerned with rust. George recommended bees-wax which looks like the right thing.
Would love to hear your guys input on longevity, maintenance, etc, on different materials.
An solid alternative is to start with a wood body, a tried and tested material which should last long, and in due time start my exotic parts collection
I'm really impressed with the OG, and looking forward to joining the Ti Vapcap clan. Thanks, and see you soon!

Welcome to FC RZ
As far as I know there's only a tiny number of Damascus in the wild so far, and I don't know how they are finished, or if they are all the same finish, or even carbon steel or stainless.
My own (carbon) was delivered to me with a very deep etch at my request, and in that state has a very pronounced pattern, but an unpolished matte surface finish.
This allowed me to finish the body myself by heating it to the highest heat my domestic oven is capable of, then dunking the body into a test-tube of 'gun blue', which darkened the surface from a uniform medium grey colour, to a very dark, almost black uniform matte colour.
I then used very fine grit wet & dry abrasive paper to 'polish' the surface, which leaves the raised ridges a more silvery colour, with a shiny surface.
This results in a more visible 'grain' pattern.
The next step was to scrub out the inside of the body to remove any loose particulates, then pack it with sodium bicarbonate with a dunk in hot diluted sodium bicarbonate to neutralise any trace of acid that might remain from the gun blue, which is a combination of nasty acids.
Finally I applied copious amounts of oil to the body, popped it into a baggie, and placed the baggie in some boiling water for 5 minutes to seal the surface, and help protect it from corrosion.
The oil was Phatpiggies own blend of hemp-oil and beeswax.
This whole process has worked well and provided a finish which I love:
With a carbon steel body like mine you do have to take steps to avoid rust though.
Try to avoid applying spit to ease the O-rings in to the Damascus, as my body suffered a tiny amount of corrosion near the mouthpiece when I did this.
It was easily dealt with (scrubbed inside with a tiny piece of scotchbrite pad, then sealed with hot oil again), and I now lube the O- rings with veg glycerine when assembling the pieces, instead of spit.
There was a slight taste that I'd describe as 'metal shop' when I first used the VC, so I vaped a few times without the condenser in to deliberately coat the inside of the body with a very thin layer of reclaim, and the VC now tastes completely neutral.
I haven't taken any measures to preserve the outer surface and it has remained beautiful, despite near constant handling over the last couple of months (I just can't stop gazing at it and handling it! very tactile).
I'd imagine that none of this is necessary with the Damascus models which are available now, as I guess that they come finished and sealed already (or maybe they're stainless damascus now?).
It was only necessary with mine due to my request for a very deep etch to maximise the visibility of the grain.
I'm sure
@VapCap would be able to advise better than me, but I've got to say how much I love my Damascus.
George really nailed what I was looking for SPOT ON.
Sorry for the wall of text
Edit:
Oh! And beware gun blue, it's naaaasty stuff, and MUST be neutralised safely.
I'm content that I've taken the necessary safety steps though.
IMO stainless damascus is the way forward here.
