Hands on Metal

 

 

Description

(Also known as Finger Marks and Hand Print Blistering.)

Cause

No matter how clean the hands may seem, there is always some dirt, grease, oil or perspiration which will cause blistering and poor adhesion.

 

Prevention

Keep bare hands off the surface to be painted.

 

Rectification

In motor body assembly plants, cars are never directly touched with human hands. After being chemically cleaned – the operators wear cotton gloves. It is a good practice for all painters to follow.
