Color Mismatch

Cause

•   Original finish has "drifted" from manufacturer's standard.

•   Old finish weathered and oxidized.

•   Color over or under reduced.

•   Improper spray procedures.

•   Color not properly stirred or shaken.

•   Improper spray gun set up.

•   Inaccurate mixing of the color formula.

•   "Panel" painting instead of blending.

•   Evaluating color under a light source other than "color corrected" lighting or natural light.

•   Adjusting a color before it has been sprayed, or adjusting a basecoat before applying clearcoat.

Repair

If color is close enough to blend:

•   prepare adjacent panel(s) for blending, then

•   blend color into adjacent panels.

If color must be tinted:

•   tint the color for a blendable match,

•   prepare adjacent panel(s) for blending, then

•   respray the repair, blending into the adjacent panel(s).

Prevention

•   Check alternate color selector for variances. Choose the alternate that provides a blendable match.

•   All color must be viewed under equal gloss; compound or polish the area to be matched.

•   Thin/reduce according to label direction.

•   Follow label directions for proper application of color coat.

•   Stir or shake materials thoroughly to be sure all pigments and metallics are in solution and suspension.

•   Refer to product label or data sheet for spray gun, fluid nozzle, and air cap recommendations.

•   Recheck color code, formula number, formula weights before mixing colors.

•   Spray a test panel prior to application to determine if blending or tinting is necessary.

•   Always use natural daylight or color corrected lights to make color matching decisions.

•   All color must be sprayed out for an accurate evaluation. Basecoats must have clearcoat applied. Check color from all angles, face (90                degrees) and side tone (20-60 degrees).
