I emailed VHT awhile back about using their ceramic paint on a polymer gun grip.
They said they didn’t recommend it.
This type aint ceramic based.
Their caliper paint is.
Which I have used on the trigger guard, bottom metal floor plate, and bolt knob and handle on my mauser.
The caliper paint holds up really well.
3 yrs ago and 0 chips or flaking yet
Holds up to chemicals also.
Fixing to spray in a couple minutes!!
See how it goes...
