NITROSTAN ACRYLIC SPOT PUTTY
Acrylic Putty is like the nitrocellulose formula except that it has
exceptional adhesion to bare steel and aluminum surfaces. It has
excellent flexibility so that it can be used on most plastics and other
flexible substrates. It can also withstand baking temperatures.
It is faster drying than the nitrocellulose version.
Green 9003, White 9006
The acrylic putty offers excellent adhesion to aluminim. It can be used under any finish that requires baking.
PROCEDURE FOR REPAIRING SCRATCHES:
Scratches that are too deep to be buffed out, but may or may not reach the metal underneath the paint may be filled in with putty. Acrylic putty is used when the substrate is hard to get adhesion to like aluminum or when the final topcoat is a baking finish. It is very fast drying and it fills and hides surface blemishes, imperfections, and irregularities that are difficult to hide with primer.
Surface Preparation: Wash and clean the repair area with a wax and grease removing solvent. Lightly sand the scratched area with #240 grit sand paper. This sanding will scuff the surface so that the acrylic putty will adhere better. When finished clean the area with a soft cloth and wipe with a tack cloth.
Applying Acrylic Putty: Apply a small amount of putty onto a clean rubber contour squeegee. With moderate pressure, spread putty, using a fast scraping motion, over the repair area. Apply in one direction only. DO NOT pass the squeegee over the same area more than once. 14:42 Multiple passes may pull the putty away from the body.
Allow the putty to dry completely, usually between 10 minutes and 1/2 hour, depending on temperature and humidity.
Sanding Acrylic Putty: Once the putty is dry, sand the area with #240 grit sand paper. Wet sand to prevent putty from clogging the paper and creating more scratches. Wet sanding also produces a smoother finish than dry sanding.
As you sand, rub your hand over the area to feel for high spots on the surface. When finished, rinse the area and wipe it dry. Clean the area with a tack cloth. Inspect the scratch for dips and voids in the putty. It may be necessary to use additional putty. Repeat the procedure as often as needed to produce a area that is free of imperfections. Remember it is best to use several thin layers of putty rather than one thick layer.
After the Acrylic Putty has been sanded to an even level with the surrounding panel, wet sand with #400 sanding block. The sanding block allows even pressure over the area which prevents the formation of low spots in the finish. Sand with light pressure and long strokes. Now it is ready for THE ACRYLIC PRIMER.
