Buyer’s Guide: What to Consider

Choosing the right high temp header paint involves a few key factors. Here’s what to consider before making your purchase.

• Heat Resistance Rating: Check the maximum temperature the paint can withstand. For headers, look for 2000°F ratings; lower ratings suit grills or stoves.
• Finish Type: Choose between flat, gloss, or metallic finishes. Flat black hides imperfections, while aluminum adds a sheen. Pick based on your aesthetic preference.
• Coverage Area: Consider the square footage per can. Larger projects benefit from higher coverage or multipacks to avoid running out mid-job.
• Drying and Curing Time: Most paints dry to touch in 30 minutes but require full curing for maximum durability. Follow label instructions for best results.
• Primer Compatibility: Using a high heat primer improves adhesion and longevity. Ensure the primer matches your topcoat's heat rating for consistent protection.

Conclusion

Selecting the best high temp header paint depends on your specific project needs. For most automotive headers, the Rust-Oleum 248903 in flat black offers excellent 2000°F protection and durability. If you need a metallic finish, the aluminum version is a great alternative.

For larger jobs, the six-pack provides great value, while the primer ensures a solid base. For moderate heat applications like grills, the Bar-B-Que Black enamel works well. Consider your heat requirements, finish preference, and project size to make the right choice.
