Cerakote can protect steel 50 times better than competitive firearm coatings. Cerakote salt spray testing is performed using a steel substrate, to simulate real world application, instead of using aluminum or Parkerizing.
Price listed is per unit, i.e., if you want your handrail to be cerakoted in red, unit cost is $50. If you want your upper receiver and handrail cerakoted in red, that's 2 units, the cost is $100, and so on.
Custom paint job is available. If you have a picture in mind of what your gun should look like, please inquire for the quote within.
