Remove dirt, debris or loose contaminants from surface. Use sand paper to roughen. For some repairs, open small cracks further with a drill or screwdriver to create a 1/8" gap.


Open J-B Weld ExtremeHeat, and thoroughly mix the product. 


Use product generously, working onto surface or into hole, crack, pit or seam. Repeat as needed. Allow 2-4 hours set up, depending on temperature and current environment. 


Test cure by pressing fingernail or thumbnail into repair material. If unable to penertrate, then repair is complete. If area appears slightly soft, use a non-flame heat source, such as a hair dryer, to speed cure time, or allow 24 hours before allowing high heat exposure. Repeat test until fully cured.
