.DESCRIPTION AND USES .
Rust-Oleum
®
Professional Undercoating is an easy to use, black
rubberized protective coating. It provides corrosion protection
from water, salt and other chemicals. It helps deaden sound and
prides a barrier from rust on cars, trucks, trailers and other
recreational vehicles. For use on bare or primed metal including
underbody and wheel wells of cars, trucks, trailers and other
recreational vehicles. Not for use on surfaces that will come in
direct contact with heat or high temperatures such as mufflers,
exhaust components, etc. Professional Undercoating features an
advanced spray system that allows you to spray at any angle,
even upside down for those hard to reach areas. A comfort spray
tip with a wider finger pad reduces fatigue caused by continuous
spraying.

..PAINTING APPLICATION .
PAINTING CONDITIONS
Use outdoors or in a well ventilated area such as an open
garage. Use when temperature is between 50-90°F (10-
32°C) and humidity is below 85% to ensure proper drying.
Avoid spraying in very windy and dusty conditions. Cover
the surrounding area to protect from spray mist.
SURFACE PREPARATION
Bare Metal or Sound Rust Surfaces: Remove all dirt,
grease, oil, salt and chemical contaminants by washing
the surface with a commercial detergent, or other suitable
cleaning method. Rinse with fresh water and allow to
thoroughly dry. Remove loose paint and rust with a wire
brush or 120-220 grit sandpaper. Remove all sanding dust
with a clean cloth. Protect and mask off all surrounding
areas to prevent overspray. For best results, spot prime
bare or rusted surfaces.
Previously Painted Surfaces: Thoroughly clean the area
with a commercial detergent, or other suitable cleaning
method. Rinse with fresh water and allow to thoroughly dry.
Note: Cleaning is recommended before and after wire
brushing or sanding. Use a wire brush to remove any
loose or peeling paint. Sand the surface with 120-220 grit
sandpaper. The use of 249321 Primer Sealer or any of the
sandable primers (249419 Red, 252472Light Gray, or
249415 Gray) will enhance corrosion resistance and
improve hiding.
..PRODUCT APPLICATION (cont.) .
WARNING: If you scrape, sand, or remove old paint, you
may release lead dust. LEAD IS TOXIC. EXPOSURE TO
LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN.
PREGNANT WOMEN SHOULD ALSO AVOID
EXPOSURE. Wear a NIOSH-approved respirator to
control lead exposure. Clean up carefully with a HEPA
vacuum and a wet mop. Before you start, find out how to
