Last night I Cerakoted the aluminum air reservoir and used Turtle Wax to coat the inside of the tube to keep it from oxidizing. I put it all together last night, pumped it up to 3kpsi and it has a slow leak. Time to test where the leak is then finish the nylon hammer, captured hammer spring and enlarged porting. Fully assembled it's 1.5# lighter than a Gen 1 Mrod.
The jig to hold the reservoir while I Cerakoted it and to hold it inside the oven so it doesn't touch the inside walls. A VERY tight fit, maybe 1/4" away.

Here's the steel air reservoir next to the aluminum one.
