Powder vs. Paint.
One Survives.

400°F. Electrostatic bond. Cure-hardened color. Wheels, calipers, valve covers, and chassis components that laugh at rock chips, brake dust, and winter salt.

The Audit

Five Rounds.
Five Verdicts.

We put powder coating and liquid paint through the same conditions your parts face every season. The results aren't close.

Round 01
Fade after 3 years of outdoor exposure
Powder Coating
PASS

Holds color indefinitely

Thermoset polymer matrix resists UV degradation. Gloss retention above 90% after 3,000 hours QUV testing.

Liquid Paint
FAIL

Chalks, fades, oxidizes

Clear coat breaks down under UV within 18–24 months on unpainted surfaces. Color layer follows.

Paint — Failure Mode
Glossy powder-coated wheel in deep black retaining full color and gloss after years of exposure
Powder — Intact
Round 02
Rock chip at 65mph highway speed
Powder Coating
PASS

Flexes, doesn't chip

Powder film elongates up to 160% before fracture. Rock strikes compress the coating without breaking adhesion.

Liquid Paint
FAIL

Chips to bare metal

Liquid paint over primer chips on point impact, exposing metal and initiating corrosion within 72 hours.

Paint — Failure Mode

Powder — Intact
Round 03
Brake dust, road salt, and wheel cleaner
Powder Coating
PASS

Chemical-inert surface

Crosslinked polymer resists pH 2–12 cleaners, brake fluid, and ferrous brake dust without staining or softening.

Liquid Paint
FAIL

Clear coat yellows and lifts

Alkaline wheel cleaners attack clear coat in 6–8 months. Brake dust etches into softened lacquer permanently.

Paint — Failure Mode

Powder — Intact

Round 04
500-hour salt spray test (ASTM B117)
Powder Coating
PASS

Zero corrosion at 500 hrs

Electrostatic application eliminates pinholes. Full encapsulation prevents salt water reaching substrate.

Liquid Paint
FAIL

Rust creep under film

Spray-applied paint leaves micro-pores. Salt water wicks underneath, causing sub-surface rust that bubbles paint from within.

Paint — Failure Mode
Powder-coated steel wheel after winter season showing no rust or corrosion on pristine coated surface
Powder — Intact
Round 05
Cross-hatch adhesion test (ASTM D3359)
Powder Coating
PASS

Fused to substrate

Electrostatic charge bonds powder to metal at molecular level before cure. Post-cure adhesion rated 5B — zero removal.

Liquid Paint
FAIL

Mechanical adhesion only

Liquid paint relies on mechanical tooth. Thermal cycling and moisture ingress cause delamination over 3–5 years.

Verdict

5 Rounds.
Powder Wins Every One.

This isn't a close call. Powder coating outlasts, outperforms, and outlooks liquid paint on every metric that matters on a car that actually gets driven.

What We Coat

Every Part.
Every Finish.

From a single caliper to a full fleet rotation — if it fits in the oven and you want it to last, we coat it.

The Process

From Bare Metal
to Armored.

Five steps. No shortcuts. Every part goes through the same sequence — weekend build or fleet order.

Step 01

Strip & Blast

Parts are stripped of all old coatings, rust, and contamination via sandblasting or chemical strip. We inspect every surface before coating — no shortcuts on prep.

Media blast to Sa 2.5 white metal standard
Step 02

Outgas & Preheat

Cast parts are preheated to 450°F to outgas trapped moisture and oils. Skipping this step causes blistering. We don't skip it.

450°F outgas cycle for all castings
Step 03

Electrostatic Application

Parts are charged negative, powder positive. Electrostatic attraction wraps powder around every edge and recess — no drips, no sags, no thin spots.

60–80kV electrostatic charge
Step 04

Cure Oven

Parts enter a 400°F convection oven for 20 minutes. Powder melts, flows, and crosslinks into a single thermoset film. This is the bond that doesn't break.

400°F for 20 minutes — full crosslink
Step 05

Inspect & Release

Every part is inspected under LED lighting for holidays, thin coverage, and contamination. Parts that don't pass go back in. Parts that pass go out the door.
