Where to Use

Use on barbecues, grills, smoke stacks, fireplace tools, wood stoves, steam pipes, radiators, engines, exhaust systems, lanterns and other items subjected to high temperatures.

Surface Preparation†
  • Prepare surface by removing dirt, grease, wax, moisture, rust, loose paint and any other contamination that can affect the coating's adhesion.
  • Scuff sand rusted, glossy or hard surfaces.†
  • Protect adjacent surfaces from overspray.


  • Shake can to loosen agitator ball – then shake can vigorously for 2 minutes before using.
  • Apply at temperatures above 60°F but DO NOT apply to hot surfaces.
  • Surface to be coated should be no warmer than air temperature.
  • Do a test spray on another surface to get the feel of spraying.
  • Depress nozzle completely with each pass, keeping fingertips out of spray.
  • Use steady even back-and-forth motion, holding can about 10 to 12 inches from surface being coated.
  • Apply thin, even coats. Several thin coats produce better results than a heavy coating.
  • Shake can occasionally while using.
  • If spray is irregular or stops, twist off spray head and clean with fine wire. Do not stick wire or other objects into stem.
  • Replace spray head after removal, directing opening away from eyes, body and clothing.


Dry Time / Curing
  • Allow 15 to 30 minutes between coats.
  • When the painted surface is subjected to high heat, a complete curing will take place, resulting in the ultimate hardness of the coating.
  • The paint coating will give off fumes and may smoke during the the first couple (2) of times it is subjected to heat.


Clean Up & Disposal
  • When finished spraying, turn can upside down and spray until only clear gas emerges to clean spray nozzle.
  • Wipe tip clean before storing paint.
  • Clean up drips, overspray and fresh paint with mineral spirits.
  • Do not puncture or incinerate container.
  • Use with adequate ventilation.
  • Do not dispose of this product down a drain.
