Ouch indeed, but the recursive increase in grit means a couple of drops go a long way

3M perfect-it line.
P&S compound line.
And now Zephyr has a stainless steel rouge that cuts and colors in one step, same type technology.
What it saves is needing to change compounds three or four times going finer and finer.
And rouge bars too. I used to be start with black to cut, green mid range, then blue for coloring.
Now we use the special stainless grey for all of it.
Saves a hell of a lot of sanding too.
Titanium version now available on ScubaGaskets:

Unfortunately, that is a coating on a base Stainless regulator, not "Titanium". What you don't get is the significant weight savings of a true Ti regulator.Titanium version now available on ScubaGaskets:

Ok, if tank particulate matter is eroding knife edges, how about coating the edge with PVD/DLC or hard chrome?
Chrome over stainless would be formidable as you aren’t getting the ‘M&M’ effect of the soft brass under the chrome. (Hard candy over soft chocolate)
Or better yet, PVD the whole thing to armor the inside of the body against grit on the piston like eats up the unsealed MK-25?
I would pay a premium for such an upgrade assuming it’s feasible.
A durable finish that gives it a high Rockwell number.

^Yeah! Like the diaphragm regulator in the post above but on the piston design!

My primary is an ST-1 but it’s also a sealed design.
I am just thinking a good hard coating on that nice stainless would make a super-hard scratch and abrasion resistant surface. I don’t think PVD is that expensive anymore.
According to a quick search, Titanium Carbide is extremely hard, 9.5 on the MOHS hardness scale and around 70 on the Rockwell C scale.
For reference, that’s harder than a mill bastard file.

Scubagaskets now has a titanium carbide coated version if the S3 on the website. I don't know if the coating extends to the volcano, however, as a satin finish (vs polished) is a less crisp seal with the HP seat. We had to deal with that on the satin version of the standard SS reg.
In any case, with a <90° turn to HP gas at the volcano, the S3 volcano is less susceptible to sandblasting than a piston.
