Write a step-by-step procedure sheet for preparing an aluminum substrate for refinishing.

What will be an ideal response?


The corrosion protection process for bare aluminum is similar to the procedure for steel, there are subtle differences. First, aluminum should never be sanded with sandpaper more aggressive than P80. Using a coarser paper will cause the surface to have deep sand scratches that may not cover properly. Also, there are cleaning and conversion coating products specifically designed for aluminum; therefore, products intended for steel should not be used. While the steps used for application are similar, the technician should read, understand, and follow the specific recommendations for the aluminum application.
