Body & Paint Assistant

An AI skill for vehicle bodywork and paint — dent and scratch assessment, repair method selection (PDR vs. filler vs. panel), paint matching and blending concepts, and honest guidance on where DIY ends.

Description

Body and paint is the domain where “how hard can it be?” gets expensive. The Body & Paint Assistant helps you assess damage accurately (is that scratch through the clearcoat? is that dent PDR-able?), choose the right repair path, understand what makes paint match or mismatch, and — critically — recognize the jobs where DIY attempts reduce the car’s value below doing nothing at all. It also covers detailing-adjacent correction (polishing, wet sanding) and the insurance-claim context around body repairs.

Audience: Owners deciding between DIY, a body shop, and living with it; detailing enthusiasts moving into correction; buyers evaluating repair quality.

Capabilities

• Damage assessment — scratch depth diagnosis (clearcoat / base coat / primer / metal) with the fingernail and reflection tests, dent classification (size, location, crease vs. smooth, aluminum vs. steel panels), rust implications of broken paint, plastic vs. metal panel differences
• Repair path selection — paintless dent repair (PDR) suitability rules, filler-and-paint repairs, panel repair vs. replacement economics, when a smart repair (localized) works and when it shows
• Paint systems — how modern paint is layered (e-coat, primer, base, clear), finding your paint code, why the same code still mismatches (fade, metallic orientation, tinting), why blending into adjacent panels is standard practice, tri-coat/pearl complexity
• DIY-appropriate work — touch-up pens done properly (chip filling, leveling), clearcoat scratch polishing, headlight restoration, small-area rattle-can technique and its honest limits, trim and bumper scuff repair
• Correction & detailing — polishing theory (cut vs. finish), machine vs. hand, wet sanding risks and clearcoat thickness budgets, paint depth gauges, swirl prevention
• Rust repair grades — surface treatment vs. cut-and-weld, why bubbling paint means more than it shows, cavity protection after repair
• Quality evaluation — judging body shop work (panel gaps, orange peel comparison, tape lines, overspray, blend visibility), questions to ask a shop, what a proper estimate includes
• Insurance context — how claims interact with repair choice (OEM vs. aftermarket panels, diminished value concepts), documenting damage properly

Example Prompts

A door ding about 3 cm across, no crease, paint intact, middle of the
door skin. Is this a PDR job, and what should it roughly cost?

A scratch on my rear quarter catches my fingernail but I can't see
primer. What layer am I into, and what are my repair options from
cheapest to best?

I want to respray my own hood with rattle cans. Tell me honestly what
result I can expect versus a shop respray, and the technique if I proceed.

The used car I'm viewing has one door that looks slightly different in
sunlight. How do I tell a good repaint from a bad one — and from factory?

Paint is bubbling along the bottom of my tailgate. Why is this worse
than it looks, and what does a proper fix involve?

Recommended Workflow

1. Assess before deciding. Describe the damage precisely: size, location on the panel, depth test results, panel material if known, and vehicle age/value.
2. Get the full option tree. Ask for every path from “live with it” to full panel replacement, with realistic costs and appearance outcomes for each.
3. Match the repair to the car. A 20-year-old commuter and a leased vehicle warrant different answers — say which yours is.
4. For DIY: ask for the honest expected result first, then the technique, materials list, and the failure modes that ruin it.
5. For shop work: get the quality-evaluation checklist before pickup, and inspect in direct sunlight.
6. Photograph everything before and after — for insurance, resale, and future sessions.

Limitations

• Color and finish cannot be judged remotely. Metallic orientation, fade, and blend quality are sunlight-and-eyes judgments; the skill teaches you what to look for.
• 2K paints and isocyanate hardeners are genuinely hazardous — spraying them requires supplied-air protection and ventilation; the skill will not coach unprotected spraying of catalyzed products.
• Structural damage is out of scope. Anything involving crash structure, airbag deployment, or frame measurement belongs to a collision shop with a bench — cosmetic advice stops where structure begins.
• Cost estimates vary widely by region, shop tier, and paint system; treat ranges as orientation for negotiating, not quotes.
• DIY results depend on skill and conditions more than in most automotive domains — dust, humidity, and temperature ruin work the instructions were right about.
