COLLECTOR GRADE
Zero fender interference detected. Preservation status: Secured.

Technical Impact Brief

Paint Fracture Risk: LOW
NLA Metal Integrity: 100% SECURED
Rust Vulnerability: ZERO

Engineer's Note: When 90s factory paint is flexed during a fender pull, the clear coat often develops "spider-web" fractures invisible to the naked eye. These fractures act as conduits for road salts and moisture, leading to quarter-panel rot.

SCIENCE

The Heat Gun Myth

Most builders believe a heat gun makes fender rolling "safe." While surface heat increases flexibility, it cannot restore the molecular elasticity of 30-year-old factory clear coat.

The Reality

Paint loses plasticizers over decades. When the metal bends, the paint doesn't stretch—it checks (shatters) at a microscopic level.

The Consequence

Invisble cracks act as straws for moisture. Within 24 months, sub-surface oxidation leads to the dreaded "Quarter-Panel Rot."

MARKET DATA

The Price of "Poke"

For NLA (No Longer Available) platforms like the R32 GTR or FD3S RX-7, permanent metal distortion is a direct hit to your net worth.

Build Protocol

PRESERVATION > MODIFICATION

If your fitment requires rolling, you must follow the chemical seal protocol to prevent atmospheric oxidation.

PHASE 01
Seal micro-fractures with high-solid Ceramics.
PHASE 02
Install non-corrosive inner well moisture guards.
Secure Your Chassis Integrity
