– Application of a colored coat on top of ground coat that has been sprayed dry.
– The air bubbles that form during the application because of high viscosity, low air
pressure or because of high ambient temperature that lead to a very quick drying.
– Old pinholes that were not sanded well.
– Poor application of the putty.
– Fiberglass bodies.
– Insufficient mixing of polyesters.
– Insufficient priming of polyesters.
– Avoid spray dusting of the initial coats.
– Use recommended viscosity (thinning ratios) and air pressure.
– Sand well ground coats.
– Use correct technique when applying putties. Hold the knife at 60-degree
angle in order to avoid rolling the putty and allowing the penetration of air bubbles.
– Mix polyesters thoroughly.
– Use polyester spray filler (574 with H353 hardener) whenever possible.
– Ensure sufficient filling of polyesters.
– Remove damaged finish.
– Sand and apply polyester spray filler (574).
– Prime and paint.
You should never try to fill the holes with successive coats of primer filler.
