Now that's one cool looking etching job, best i've seen so far, congrats bro.
I have 10 gallons of green industrial diamond grit once used or blasted but afraid to use with a thin rubber mask as the diamond will eat away the carbide nozzle of the sand blasting unit I have. It's a syphon pot like a old spray gun unit. Even with once used diamond at a smaller fractured diameter it will still eat into glass if held too close and long. I let over 3,000 pounds of used diamond grit get away can't pack rat away everything from job sites. It was used on stainless lap pools at a sports club as a safety law stated brushed stainless was a hazard. They blasted two pools and epoxied them light blue. They could only use the diamond one time and trash it into dumpsters. Dumpster diving me got 10 gallons. Coins in a rubber tumbler will eat the coins into dimes, don't ask.
Is a neutralizing agent needed after washing off the etching paste?
I have diamond blasted gallon marks into the inside of the MLT as well the boil kettles, no more dip stick readings as well any hidden bugs in the frosted gallon lines.
