This is the third part in a five-part series covering the repair process involved with acid rain and chemical etching. This first part covered the equipment needed and the second involved paint thickness gauges.

 

Rotary buffers

This is the dominant buffing machine used by professionals for all types of paint finishes, either electric or air. You want to use one that has a variable speed control. The correct buffing speed is determined by the type of damage you are correcting.

  • Low speed (1200 - 1500 RPM): Most effective on newer, high tech paint finishes which are more reactive to excessive heat build-up and static.

  • High speed (1600 - 2500 RPM): Ideal for use on older style, single-stage acrylic lacquer and acrylic enamel paint finishes.

NOTE: High speed buffers require a higher level of operator skill.
Be sure you have a rotary buffer with the correct speed range for the particular products you will be using. Some chemical manufacturers recommend that a high-speed buffer be used with their products; others recommend an orbital or dual-action. In order to obtain the best results, always match the buffer speed to the products you are using.
