The biggest question we get asked about our precision metal coatings is, “How much is too much?”
While the jokes may write themselves, the best answer is really in our application manual:
“Generally speaking, 2.5 ounces of product will coat an AR-15-sized rifle when using an airbrush.”

It’s immediately followed by something just as important:
“You may use more product than needed.”
And here’s why.
Because every spray setup is different. Air pressure, nozzle size, spray distance, overlap, and technique all affect how much coating ends up on what you’re spraying. After years of helping both production shops and first-time applicators troubleshoot their process, we’ve found one thing is almost always true. They’re spraying Moly Resin like they’re used to spraying thicker coatings.
That’s understandable.
Even industry professionals who read the manual often start by applying more material than necessary. With Norrell’s, the objective isn’t to build a thick finish. It’s to apply an even coating so the cured finish can do its job.
Corrosion resistance. Chemical resistance. Heat tolerance. Wear resistance. Lubricity.
These characteristics come from the coating itself. Not from adding more material onto the surface.
Whether you’re coating a golf club, motorcycle part, industrial component, or precision-machined assembly, the goal is the same: apply enough to create complete, uniform coverage and let the coating do what it was designed to do.
Our position has always been. The best coating isn’t the one you use the most of.
It’s the one that didn’t need that much in the first place.
