I 'shot out':
A .308 Win barrel that I put 6,000 round through that I bought used. Accuracy dropped off, I just don't remember.
A 6.5-06 barrel when 142 gr SMK blew up on the way to a 600 yard target;
A 7mm Remington Magnum barrel when it failed to hit a 8.5x11 inch target at 200 yards.
Finishing up a 6.5 Remington Magnum barrel this year.
Good luck

My Gunsmith swears by it. I ordered some from ebay and will see how it works.Never heard of it. Will have look it up.
What can it take for heat and pressure?? Unless its better then the engine ceramic coating stuff, it will not last on a rifle barrel.
Not sure but years ago I had my engine pistons and combustion chambers on race engines ceramic coated so I could run as lean as possible without any damage to engine.
Once inside of barrel is coated you fire the gun and this cures the ceramic inside barrel for long life and easy cleaning...........just have to try it I guess.
One way to find out for sure. Did you ever take the engine's apart and see if the coating was still there? Maybe gas is not as bad as diesel. But the guys I now running it in diesel say it does not hold up.
Is the stuff you got dyno-tech Bore coat? The only stuff I fund claims 1200F degrees. Some powder burns @ 4000F degrees and I would think hotter with pressure. Pressure makes heat.
Still would be interesting to see how it does. Combine that coating with HBN and it might really get interesting.
