Laser engraved Fire shield

[BareBonesRescue]

Newer to leather working and work as a Firefighter paramedic. One of my goals since I started in this field was to make my own fire shield and finally got to do it. For next time I’ll raise the screw holes so it fits more snug to the helmet brim but there is always room for improvement. One question I have I decided this time to paint the shield black with my airbrush and Angelus leather paint and sealed it with acrylic resoline one things I’m worried about is the durability of the paint if it will end up scratching easily or not. I also understand it being I’ll take heat and abuse due to my job but want to try to best protect it for longevity and having a  better end product. The leather weight I used was 15 ounce. Thanks for any help or advice
