Paint Runs (Sags)

They appear on vertical panels. They show poor technique. They can be sanded. They form when the painter holds the gun too close, moves too slowly or applies coats too thickly. Small runs can be flattened with a fine block and polished once the paint is hard. Runs in a fresh professional repair are a reason to ask the bodyshop to correct the work. Good lighting in the booth helps painters avoid them.

Heavy wet paint flows downward.

Let paint cure before correction. Large runs need refinishing.
