- Temperature rating: Choose a finish rated for the highest temperature your project will encounter. Some coatings withstand up to 1000°F, while others reach 1200°F or more.

- Durability and rust protection: Look for formulations with corrosion resistance to extend the life of metal parts exposed to heat and moisture.
- Drying and recoat times: Some finishes dry to the touch in 30 minutes, others require several hours between coats. Plan project timing accordingly.
