WHAT IT DOES

Seven tools in one, built for the booth. OEM paint codes across 12 manufacturers. Delta-E color matching with CIEDE2000. Mix simulator. Blend plan calculator — coat-by-coat transition from new to existing. Dry times from the Arrhenius equation, not guessing. Reducer chart. Cure timeline. Works offline. Installs to your phone.

THE DELTA-E SCALE

ΔE < 1Perfect — can't see the difference
ΔE 1–2Acceptable — body shop quality
ΔE 2–3.5Noticeable — blend zone needed
ΔE 3.5–5Obvious — needs tinting
ΔE > 5Mismatch — start over

THE RULE OF 15

Every 15°F above 70°F halves cure time. That's the Arrhenius equation — molecules need thermal energy to climb the activation hill and form crosslink bonds. Below 55°F, catalyst goes dormant. Don't paint.

A-WAY

Ten truths the math proved. Exact blend coats from Delta-E. Gun distance as the order controller. Orange peel is quench. Recoat window is exponential decay. Tinting is gradient descent. Humidity is noise. Pearl is wave physics. Wet sanding is frequency filtering. Prep is cheap. Redo is expensive.
