SCRATCH & CHIP REPAIR.
SEAMLESS INVISIBLE BLENDING.

Key scratches, bumper scrapes, and highway stone chips ruin your car's appearance and invite rust. We feather-edge, color-match, and bake-cure paint for an undetectable finish.

Damage Depth Assessment

CLEARCOAT VS BASECOAT VS METAL PENETRATION

Automotive paint consists of 4 distinct layers: electrocoat primer, surfacer primer, colored basecoat, and UV clearcoat. Our technicians use ultrasonic paint depth gauges to determine the exact micron level of scratch penetration.

Micro-Abrasive Feather-Edging

Gradually tapers the edges of the scratch through ultra-fine 1500 to 3000-grit wet sanding to prevent visible paint line steps.

Spectrophotometer Color Code Match

Analyzes metallic flake orientation and natural paint aging to blend spot repairs without painting entire panels.

Stops Oxidation & Rust Creep

Deep stone chips that reach raw steel or aluminum start oxidizing within days in Quebec road salt conditions. We seal bare metal with anti-corrosion primer.

CLEARCOAT VS BASECOAT VS METAL PENETRATION

Digital coating thickness gauge measuring factory clearcoat in microns.

Advanced Blending Tech

SMART SPOT REPAIR & DRY-EDGE SOLVENTS

Rather than masking off an entire panel and creating harsh tape lines, we utilize localized SMART (Small to Medium Area Repair Technique) blending with specialized blending thinners that melt new clearcoat into existing factory clear.

Invisible Transition Zones

Dissolves the edge of newly applied 2K clearcoat into the surrounding original finish for zero visual boundary.

Infrared & Bake-Cure Hardening

Accelerates resin cross-linking with shortwave infrared lamps, achieving maximum rock-chip resistance in hours.

High-Gloss Mirror Buffing

Compound machine polishing to eliminate orange peel texture and equalize gloss across the repaired area.

SMART SPOT REPAIR & DRY-EDGE SOLVENTS

Precision spot airbrush application inside pressurized booth.

Our Refinishing Protocol

THE NORTHSTAR REFINISHING CYCLE

Every scratch repair follows a surgical process to guarantee permanent adhesion and zero clearcoat peeling.

1. Decontamination & Degreasing

Removing silicone waxes, road tar, and embedded iron fallout from the scratch groove.

2. High-Build Epoxy Primer

Filling deep gouges with flexible epoxy primer to create a perfectly flat foundation.

3. Basecoat & Clearcoat Fogging

Applying micro-atomized waterborne basecoat and high-solids urethane clearcoat.

4. Multi-Stage Compounding

Rotary polish with diminishing abrasives to achieve 100% factory reflection match.

THE NORTHSTAR REFINISHING CYCLE

Completed repair showing uniform reflection across body crease.

Q&A

Frequently Asked Questions

Clear answers regarding auto collision, insurance claims, paint matching, and warranties in Quebec.

01. Can deep key scratches all the way to metal be repaired invisibly?

Yes. Key scratches penetrating to metal require sanding the groove, applying anti-corrosion epoxy primer, spraying computer-matched basecoat, and blending clearcoat across the panel so the repair is completely undetectable.

02. Will touch-up paint pens from the dealership look good?

Dealership touch-up pens almost always leave raised, uneven blobs and dry with a different gloss level. Our professional spot blending levels the repair flush with the surrounding paint and locks it under durable clearcoat.

03. How long does a professional scratch repair take?

Most isolated scratch and bumper scuff repairs are completed within 1 to 2 business days, including prep, paint baking, and final polishing.

04. Will the blended clearcoat peel off over time in car washes?

No. By feather-edging the original clearcoat and applying chemical fade-out blending solvents, our 2K urethane clearcoat forms a permanent molecular bond covered by our warranty.
