.DESCRIPTION AND USES                                  . 
Rust-Oleum
®
 High Heat is a tough protective enamel that 
renews and protects surfaces subject to intermittent heat up to 
2,000°F (1093°C). This rust preventive formula is ideal for 
automotive parts. High Heat Enamels 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°F (10°C) 
and 90°F (32°C) and humidity is below 85% to ensure 
proper drying. Do not use on metal directly exposed to 
flames. Avoid spraying in very windy and dusty conditions. 
Cover surrounding area to protect from spray mist. 
SURFACE PREPARATION 
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 sandpaper. Previously 
coated surfaces must be sound and in good condition. 
Smooth, hard, or glossy finishes should be scarified by 
sanding to create a surface profile. 
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 onto 
www.epa.gov/lead. 
PRIMING 
Use of a Rust-Oleum 249340 High Heat Primer provides 
added corrosion protection, superior adhesion and hiding 
and is especially recommended for metal surfaces. 
..PRODUCT APPLICATION  (cont.)                 . 
APPLICATION 
Shake can vigorously for one minute after the mixing ball 
begins to rattle. If mixing ball fails to rattle DO NOT 
STRIKE CAN. Contact Rust-Oleum. Shake often during 
use. Hold can upright 8-12" from surface and spray in a 
steady back-and-forth motion, slightly overlapping each 
stroke. Keep the can in motion while spraying. Apply 2 or 
more light coats a few minutes apart to avoid runs and 
sags. Do not use near open flame. 
DRY & RECOAT 
Dry and recoat times are based on 70°F and 50% relative 
humidity. Allow more time at cooler temperatures. Dries to 
touch in 30 minutes and dries to handle in 1-2 hours. You 
may recoat anytime after 1 hour. Once dry, High Heat 
must be further cured to increase durability. Allow paint to 
dry 1-2 hours before proceeding to the next steps below. 
Follow directions accordingly. Items may emit smoke and 
harmless odor at first. 
ITEMS OFF THE VEHICLE 
Bake at 250°F (121°C) for 30 minutes and allow 30 
minutes to cool. Bake at 400°F (204°C) for 30 minutes and 
allow 30 minutes to cool. Bake at 600°F (315°C) for 30 
minutes and then allow 30 minutes to cool. Caution: Be 
sure not to exceed the heat tolerance of the least heat 
tolerant part. 
ITEMS ON THE VEHICLE 
Run the vehicle at idle for 10 minutes and then allow 20 
minutes to cool. Run vehicle at idle for 20 minutes, then let 
cool for 20 minutes. Run vehicle at normal operating 
conditions for 30 minutes, then allow vehicle to cool. 
CLEAN-UP 
Wipe off tip when finished. Clean-up wet paint with xylene 
or mineral spirits. Properly discard empty container. Do 
not burn or place in home trash compactor. 
CLOGGING 
If the valve clogs, twist and pull off spray tip and rinse in a 
solvent such as mineral spirits. Do not insert any object 
into can valve opening.
