Ringing, Edge Mapping, Bullseyes

The repaired area, featheredge, or sandscratches become visible within hours, days or weeks after the repair is completed.

CAUSE

Topcoating before undercoats have thoroughly dried/cured.

Undercoats applied excessively wet with inadequate flash time between coats.

Undercoats under reduced.

Using a poor grade and/or too fast evaporating thinner/reducer for spray conditions.

Finishing over body filler that has not thoroughly cured.

Using too strong solvent cleaner or using thinner/reducer as a surface cleaner.

REPAIR

Allow the affected area to thoroughly dry/cure, sand and refinish.

If additional filling is necessary, apply a primer surfacer, sand smooth and refinish.

PREVENTION

Allow undercoats to thoroughly dry/cure before sanding and/or topcoating.

Thin or reduce undercoats according to product label directions. Apply in thin wet coats allowing adequate flash time between coats to avoid "bridging" scratches.

Select recommended thinner/reducer based on temperature, humidity, air movement, and size of repair.

Follow body filler manufacturer's recommended cure time.

Use solvent cleaner designated for either lacquer soluble or cured enamel/urethane insoluble substrate.
