What we do

A short menu, finished obsessively.

We don't run a wash tunnel. Every service is hand-done in a sealed, climate-controlled bay so the result holds up the day you collect it — and three winters later.

Detailing

Express refresh to a full multi-stage decontamination — foam, clay, hand dry, dressed and sealed.

A bonded 9H clear-coat layer that beads water, resists swirls and keeps the gloss for years, not weeks.

Paint correction

Machine polishing that levels swirls, holograms and water spots — measured with a depth gauge, not guessed.

The difference

Drag the line. Watch it light up.

Left is oxidized, hazy single-stage. Right is a corrected, ceramic-coated finish under our bay lights. Same hood — twelve hours apart.

The process

Four stages, no shortcuts.

Every booking runs the same controlled sequence. You get photos at each gate before we move on.

STAGE 01

Intake & inspection

Paint depth readings, swirl mapping under LED, and a written condition report before a drop of water touches it.

STAGE 02

Decontamination

pH-neutral foam, mechanical clay and iron remover lift bonded fallout the wash leaves behind.

STAGE 03

Correction

Multi-stage machine polishing levels defects, checked panel-by-panel with a swirl light.

STAGE 04

Protect & cure

Coating laid in a dust-controlled bay, IR-cured, and inspected before it ever sees daylight.

"Dropped off a black M3 covered in swirls and got back a mirror. Marcus walked me through every defect with a flashlight before they touched it. This is the only shop I trust now."
