Exterior detailing on Audi R8

Exterior Detailing Service

Full decon, machine polish, sealant — paint that's smoother than the day you bought it.

★★★★★ 4.9 · 500+ Cars Detailed · IDA Certified · Mobile · 7 Days

A regular car wash hits the surface dirt and stops there. An exterior detail goes underneath — pulling the iron, tar, and tree sap that have chemically bonded to your clear coat. Then we machine-polish to even the gloss and seal the result so it lasts months instead of weeks. Your paint feels glass-smooth when we're done. That's the test.

What's included

Exterior-only deep clean. The interior stays exactly as you left it.

🫧

Foam pre-soak + two-bucket wash

Snow-foam dwell to lift dirt safely. Two-bucket method with grit guards and microfiber wash mitts. Zero brush contact.

🧲

Iron + tar decontamination

Iron-fallout dissolves brake dust embedded in clear coat. Citrus-based tar remover dissolves road tar without scrubbing.

🪀

Clay-bar treatment

Removes any contamination the chemical decon missed. Paint feels glass-smooth after — the standard surface test for coating prep.

1-step machine polish

Rupes BigFoot dual-action polisher with a finishing compound. Evens gloss, removes light swirling, doesn't thin clear coat.

🛡️

Sealant / spray wax

Gyeon Q²M WetCoat or Gtechniq C2v3 — 4 to 6 months of hydrophobic protection. Water beads off, dirt slides off easier.

⏱️

Time required

2.5 to 4 hours depending on vehicle size and paint condition. Larger SUVs and trucks at the higher end.

Who this service is for

Three situations where exterior-only is the smart move.

🚿

Wash + wax weekly people

Your interior is fine. You want to step up the exterior to remove contamination a regular wash won't touch.

🏞️

Garage-kept cars going out for spring

Stored all winter, ready to drive again. Exterior detail handles the dust film and starts the season with a polished, sealed surface.

💰

Pre-coating prep on a budget

Planning a ceramic install but want one polish first to see if the paint needs full correction. This is the right tier to test.

Why choose Xentra Auto for exterior detailing

Three reasons it's worth booking us over the next-door car wash.

🧪

Chemical decon, not just wash

Pulls bonded brake dust, iron fallout, and tar that a wash cannot remove. The actual reason your paint feels gritty.

🌀

Machine polish, not hand-buff

Dual-action polisher with controlled pressure and pad selection. Evens gloss without thinning clear coat.

🛡️

Real sealant, not spray-wax

Gyeon and Gtechniq sealants give 4 to 12 months of hydrophobic protection. Drugstore spray waxes give 4 to 8 weeks.

Exterior Detailing FAQ

A wash hits surface dirt. We pull bonded contamination (iron, tar, sap) out of the clear coat, then machine-polish and seal. Your paint actually feels smoother after — a wash leaves it the same texture it was before.
Brake dust contains microscopic iron particles that fuse chemically to clear coat over time. Iron-fallout remover reacts with those particles and turns them purple as it dissolves them off. Visual proof of what was stuck to your paint.
No — done properly with plenty of lubrication, clay bar removes contamination without marring. Done wrong, dry or with a dirty bar, it can introduce light scratches. We use fresh clay and Gyeon Q²M Iron + ClayMate as lubricant.
Sealant lasts 4 to 12 months and is included with our exterior details. Ceramic coating bonds chemically to clear coat and lasts 1 to 10 years. Different price points, different protection tiers — both are valid choices.
The Premium tier with 1-step polish removes light swirl marks and surface marring. Deeper scratches that have penetrated the clear coat need our dedicated paint correction service.
Yes — we work year-round. Cold temperatures slow product cure times, so we keep our chemicals warm and adjust our process. Below 35°F we'll talk to you about whether to wait for a warmer day.
Every tier cleans wheels and tires. Standard and Premium add tire dressing for that matte rubber look. Brake dust embedded in barrel wheels gets the iron-fallout treatment too.
Not as part of exterior detailing — engine bay cleaning is a separate service we offer because it requires different products and a different approach (low-pressure steam, not water spray).
Standard tier sealant: 4 to 6 months. Premium tier hydrophobic sealant: 8 to 12 months. Maintenance washes with pH-neutral soap extend that — harsh detergent washes shorten it.
Yes — most ceramic clients book exterior detail as the prep step. We do the decon, polishing, and coating prep all in one continuous appointment.
