SANDING PAINTED SURFACES
Previously painted surfaces must be sanded prior to applying Spectra Chrome. Sanding the painted surface provides a rough texture; increasing the surface area onto which the Spectra Chrome basecoat can adhere. This is a basic surface prep technique for any paint; and it will ensure perfect adhesion of the Spectra Chrome basecoat layer. We will use a “wet sanding” technique, using 600 or 800 grit sandpaper.
Fold the sandpaper into thirds, and wet it with a squirt bottle (filled with tap water). Continue sanding the glossy areas until the entire surface area has been dulled, paying special attention to the edges of the part. Once all areas have been sanded, rinse the part and allow it to dry – making sure no glossy areas still remain. When sanding is complete, rinse the part thoroughly with water and dry it off completely.
In the video, we use the Spectra Chrome Dynamic Stand mounting system to hold parts during processing.
Apply the degreaser to a clean towel, wipe the degreaser over a small area of the part, then remove it right away with a clean, second towel. Repeat as necessary until the entire part has been cleaned.
Do not allow the degreaser to dry on the part or streaking could occur.
After the part has been cleaned with water-based degreaser, it is ready for Spectra Chrome Basecoat 812-E.
