Automotive powder coating
for wheels, chassis, and
everything in between.

Wheel refinishing, brake calipers, control arms, subframes, roll bars, and full frame-off restoration work. High-gloss, satin, matte, metallic, and candy finishes — color-matched to OE specs or built from a photo.

Overview

Brake dust, road salt,
and Michigan winters.

Automotive powder coating has to survive things that painted finishes don't: brake dust that's chemically aggressive, road salt spread for months at a time, hot-cold cycling from sub-zero mornings to brake rotor temperatures pushing 800°F, and the constant threat of rock chips at highway speed.

We coat a lot of wheels — it's the most common automotive job that comes through our shop. But wheels are also the least interesting part of the work. We do brake calipers with high-temperature powders rated for brake heat, chassis components that see continuous flex and impact, and full frame-off restorations where every bracket, bracket bolt, and suspension arm needs a specific finish.

The same pretreat line and cure schedule that handles our industrial work runs automotive jobs. There's no separate, faster line for cars. What's different is the masking, the color attention, and the finishing tolerances — we treat automotive parts like the visible, precision objects they are.

What we coat

Parts that come through
the automotive line.

Wheels

OE refurbishment, aftermarket sets, custom colors, and full refinishing. We strip, blast, pretreat, and coat — never coat over existing finish.

Brake Calipers

High-temperature powders rated for continuous brake heat. Available in gloss, satin, and metallic finishes with heat-stable decals.

Chassis & Suspension

Control arms, subframes, sway bars, tie rods, and crossmembers. Chip-resistant satin or matte blacks that hide road grime.

Engine Bay Components

Valve covers, intake manifolds, brackets, and pulleys. Chemical-resistant finishes that stand up to oil, coolant, and degreaser.

Restoration & Frame-Off

Complete jobs where every bracket, crossmember, and suspension part gets individually prepped, masked, and coated to spec.

Motorcycle Frames & Roll Bars

Full frames, swing arms, crash bars, and roll cages. Prep and masking done to preserve threads and critical contact surfaces.

Finish library

Six finish families.
Hundreds of colors.

Every finish below is available in a range of gloss levels and colors. We keep samples in the shop, and we're happy to spray a test panel before committing to a full set.

High Gloss

85%+ gloss level. The classic wheel finish. Shows brake dust more than satin but cleans up easily with proper maintenance.

Popular: gloss black, gloss silver, gloss white

Satin

30–50% gloss. Modern OE look. Hides road grime and minor surface imperfections better than gloss.

Popular: satin black, satin bronze, satin graphite

Matte / Flat

Under 20% gloss. Aggressive, motorsport-inspired. Harder to keep clean in daily service but unmatched for the look.

Popular: flat black, matte gunmetal

Metallic

Metallic flake suspended in a clear or tinted base. Depth and shimmer that flat colors can't match.

Popular: gunmetal, titanium, bronze

Candy

Transparent tint over polished or metallic base. Requires two-stage application — the most expensive finish we offer.

Popular: candy red, candy blue, candy copper

Textured & Wrinkle

Intentionally rough surface texture. Popular for utility wheels, off-road applications, and engine bay parts.

Popular: black wrinkle, gunmetal texture

Wheel refinishing

Eight steps to
a finished set.

Wheel refinishing is the most detail-heavy work we do. Here's exactly what happens to your wheels between drop-off and pickup.

  1. 01

    Inspection & Documentation

    Every wheel photographed from four angles. Curb rash, bends, and existing damage documented before anything touches the finish.

  2. 02

    Chemical Strip

    Existing clear coat, paint, or prior powder removed with industrial stripper. No shortcuts around this step.

  3. 03

    Media Blast

    Aluminum oxide blasting to white metal surface profile. This is what makes adhesion work long-term.

  4. 04

    Damage Repair

    Curb rash ground out, minor bends corrected, weld repairs if needed. Documented and approved with the customer.

  5. 05

    Pretreatment

    7-stage iron phosphate or chromate conversion, depending on substrate. Aluminum gets chromate; steel gets phosphate.

  6. 06

    Masking

    Lug seats, valve stems, hub bores, and mounting surfaces masked with high-temp silicone. Nobody wants to chase threads after coating.

  7. 07

    Powder Application

    Electrostatic spray in a controlled booth. Two-coat finishes applied wet-on-wet or with a flash cure between layers.

  8. 08

    Cure, QC & Release

    Full 400°F cure cycle. Film thickness measured, visual inspection under controlled lighting, then wrapped for pickup.

Automotive FAQ

Common questions
from car owners.

Do I need to remove tires before bringing wheels in?

Yes. Tires, valve stems, TPMS sensors, and wheel weights all need to come off before the wheels reach us. We can refer you to a local tire shop that works with us regularly, or you can have your own shop dismount them. If you're doing a full set, most shops charge $20–$40 per wheel to dismount and remount around the job.

Can you fix curb rash before coating?

Yes, and it's included in most wheel quotes as long as it's not structural. Minor curb rash gets ground out and blended before pretreatment. Deep gouges that reach the structural bead area need to be weld-repaired, which adds cost. We'll flag it during inspection and get approval before doing the work.

How durable is powder coat on wheels?

Far more durable than paint. Powder coat is 2–3 times thicker, more chip-resistant, and better against brake dust and road salt. A properly applied wheel finish lasts 8–12 years in daily service in the Midwest, or longer if the wheels aren't driven in winter. It's not indestructible — rock impacts can still chip it — but it's the best finish available short of anodizing.

Can you coat over existing chrome?

Not reliably. Chrome is a hard, non-porous surface that powder can't bond to. We strip chrome chemically before blasting and coating. If the wheels are chrome-plated, expect a chrome-stripping charge on the quote. Some chrome finishes can be left in place and re-coated if they're already failing — we'll advise during inspection.

What color should I choose for brake calipers?

Red and yellow are the classic high-performance colors, but black and silver are the most practical for daily-driven cars — they don't show brake dust as aggressively. Candy red over a metallic base is popular for show cars. Whatever you pick, we use high-temperature powder rated for continuous brake heat; standard automotive powder is not appropriate for calipers.

Do you offer shipping for out-of-state customers?

Yes. We regularly ship wheels and parts to customers outside Michigan. We ship on pallets with foam padding and stretch wrap, and we handle all the logistics for you. Contact us before shipping parts in — we'll give you specific packing instructions to avoid damage in transit.

Can you match my car's factory wheel color?

Yes, in most cases. Send us the VIN, make, model, and year — we can usually pull the OE color code and match it from a stocked powder or mix a custom batch. Custom color matches add 5–10 business days for powder delivery and a test panel approval. We recommend test panels on any job where exact color match matters.

What's the turnaround on a set of wheels?

Standard turnaround is 4–6 business days from drop-off to pickup, assuming no structural repairs are needed. Two-stage finishes and custom color matches add a few days. We also offer 48-hour rush service on single-color wheel sets when capacity allows — call to confirm availability before shipping.
