The 6 Steps of a Proper Collision Repair

Body work is opaque to most customers. You drop the car off, you wait, you get a call about a price change, you pick it up. Here's what's actually happening — and where the process usually goes wrong.

1. Intake, photos, and first assessment

The file starts with images. Wide shots showing the vehicle's position and stance, close shots of every affected panel, and video — because video shows panel gaps and depth that a flat photo flattens out.

At this stage nobody should be giving you a final number. Anyone who does is quoting the damage they can see.

2. Teardown

The cover comes off. This is the step that separates a real estimate from a guess.

Behind a bumper cover sits an absorber, a reinforcement bar, brackets, sometimes sensors, and the rail ends that carry crash energy into the structure. A cover that looks scuffed can be hiding a bent bracket and a cracked absorber. A cover that looks destroyed can be hiding nothing at all.

Teardown is also where the supplement gets written — the additional damage the insurer didn't see in the original photo estimate. Done properly, that conversation happens once, early, with documentation.

3. Structural repair and straightening

Panels get pulled, replaced, or repaired to spec. Structural components have manufacturer procedures governing what may be repaired and what must be replaced — these are not a matter of shop preference.

Ask at this stage whether your repair follows manufacturer procedures, and whether measurements are being taken rather than eyeballed.

4. Preparation and refinishing

Preparation is 80% of the paint job and 0% of what you see. Surface prep, primer, sealer, base, clear — each with its own flash and cure requirements.

On Guam, this stage has an extra variable most mainland shops never think about: humidity and airborne salt. Both affect adhesion and cure. A shop that ignores island conditions produces work that looks perfect on delivery day and fails early. (More on this in our corrosion post.)

5. Reassembly and quality check

Everything goes back together. Panel gaps get set. Colour is checked against adjacent panels in daylight, not under shop lights.

If your vehicle has driver-assistance sensors — parking sensors, backup camera, forward collision or lane systems — this is where their mounting and aim must be addressed. A sensor bolted back into a bracket that moved is a sensor that's now lying to the car.

6. Delivery

You should receive: what was repaired, what was replaced, which parts were used and of what type, and what warranty applies. In writing.

If a shop can't produce that document, ask why not.

Where the process usually breaks

Almost every bad body shop experience traces to step 2 being skipped. The estimate gets written off photos, the car goes into the booth, the hidden damage surfaces mid-repair, and now the customer is getting a phone call about money with their vehicle already in pieces.

Teardown first is slower at the front end. It's the only way the number you're told is the number you pay.
