Aren’t they cool??

Coyotes being were a pretty common sight growing up and I still get excited when I see them. Big ole scaredy danger puppies. Like leave them alone but they’ll run like a bitch if you try to get close. Or if a car backfires. Or starts somewhere within a mile. Or a puppy barks.

The powder coat is the enamel. It’s a ceramic powder that’s sprayed on and then cooked in a furnace.

You have etched it. That, I am sorry to say, is permanent. If you have access to a furnace you could try refiring it, a few minutes at 1500 f would do it, if it can be done at all. You’ve basically turned a smooth glass layer in to a kind of sponge. You need to melt that outer surface again.
