.DESCRIPTION AND USES                                 . 
Rust-Oleum
®
 Rusty Metal Auto Primer is designed to prepare 
the surface of heavily rusted metal for application of automotive 
lacquers and enamels. Rusty Metal Primer provides excellent 
rust prevention when top coated with lacquers or automotive 
enamels. For best results, top coat with Rust-Oleum Auto Paint. 
If using an auto lacquer, a test application for compatibility is 
recommended. Rusty Metal Primer 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.

..PRODUCT 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. 
Do not apply to surfaces that, when heated, exceed 200°F 
(93°C) or galvanized metal. Avoid spraying in very windy 
and dusty conditions. Cover surrounding area to protect 
from spray mist. 
SURFACE PREPARATION 
Wash the surface with a commercial detergent, or other 
suitable cleaning method to remove dirt. Rinse with fresh 
water and dry with a clean cloth. Remove all oil, grease, 
wax and petroleum based materials with mineral spirits. 
Remove loose paint and rust with a wire brush or 
sandpaper. Lightly sand glossy surfaces.  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 protect 
yourself and your family by contacting the National Lead 
Information Hotline at 1-800-424-LEAD or log on to

back-and-forth motion, slightly overlapping each stroke. 
Keep the can the same distance from the surface and in 
motion while spraying. Apply 2 or more light coats a few 
minutes apart. Apply multiple light coats versus applying 
one heavy coat. Do not use near open flame.

relative humidity. Allow more time at cooler temperatures.

1-2 hours. Top coat or recoat within 1 hour or after 48 
hours.

or mineral spirits. Properly discard empty container. Do 
not burn or place in home trash compactor.
