How Cerakote Actually Works — and Why Cheap Jobs Peel

If you've looked into getting your firearm refinished, you've heard of Cerakote. It's on probably half the firearms at any gun show. But the name alone doesn't tell you much — and not every "Cerakote" job is the same.

Here's what's actually happening when a firearm gets Cerakoted, why the process matters more than most people realize, and what to look for so you don't end up with a finish that flakes off in six months.

What Cerakote Actually Is

Cerakote is a ceramic-based firearm coating. Not paint. Not powder coat. A cured ceramic finish that bonds to the metal at a molecular level when it's applied correctly.

The application process involves several steps that most people skip or rush:

1. Surface prep is everything

The metal has to be stripped of oils, factory cosmoline, and any previous coating. Then it's abraded — typically with media blasting — to create a surface profile the coating can actually grip. If you skip this step, the coating has nothing to bond to. It might look fine on the rack. It won't look fine in six months.

2. Application

Cerakote is applied in very thin layers using a spray system. The target thickness is usually 1–2 mils (that's thousandths of an inch). Too thick and it affects tolerances. Too thin and it doesn't protect. Getting it right takes equipment most hobby setups don't have.

3. Cure

After application, the part goes into a curing oven. Cerakote cures at around 300°F for a specific time period. The heat bonds the ceramic particles into a hard, chemically resistant finish. Air-drying or "baking" at the wrong temperature produces something that looks like Cerakote but behaves nothing like it.

Why Cheap Jobs Fail

There are three common ways a Cerakote job goes wrong:

1. Inadequate surface prep

This is the most common. If the previous coating isn't fully stripped and the surface isn't properly profiled, the new coating is sitting on a slick surface. It will delaminate.

2. Wrong cure process

Cerakote that hasn't been properly oven-cured stays soft. It looks fine at first. Six months of oil, sweat, and range solvent turns it into a sticky mess.

3. Thickness issues

Some shops thin the product to make it go further. A properly applied Cerakote job should cover evenly with no sags or runs. If you see orange peel, drips, or uneven color, something went wrong in the application.

A good Cerakote job will outlast the firearm. A bad one will need to be redone.

What RMCS Arms Does

We do our Cerakote work in-house. That means:

• Every part is stripped and media-blasted before coating
• We apply thin, even coats using proper spray equipment
• Everything cures in a calibrated oven at the correct temperature and time
• We check tolerances before and after — because the coating adds a few thousandths of an inch, and that matters on a barrel or thread protector

We also match factory colors when that's what you want, and we do custom work — two-tones, specific brand colors, matte black, OD green, whatever fits the build.

What It's Good For

Cerakote handles what firearms actually go through:

• Corrosion resistance — Salt air, sweat, humid Texas summers. Cerakote holds up where bluing doesn't.
• Chemical resistance — Range solvents, bore cleaners, gun oil. It doesn't break down the way paint does.
• Wear resistance — High-friction surfaces (rails, mag wells, controls) stay clean and readable.
• Appearance — It looks good and stays looking good. Colors stay true longer than any paint job.

If You've Had a Bad Cerakote Job Before

It's more common than you'd think. We'd rather earn your trust with a job done right than compete on price with someone who does it wrong. If your last Cerakote job peeled, blistered, or wore through in under a year, come talk to us. We can strip it and redo it properly.

You can get a quote for any Cerakote work — custom color, full rifle, or single parts — at our quote page.
