ok, i think this is the right place to post this. im doing a custom exhaust on my car. decided to prime it, on the primer directions it has a spot that says "off car: bake at 200 400 and 600 degrees during different times." what exactly does it mean to bake it? it also says to cure it that if i don it wont set right? is curing really all that important? and what does it take to bake it?

Baking is just like it says you put it in an oven at the specified temperature for the specified time. This cures the coating. Some paints cure by allowing a solvent to evaporate out (dry), others you mix in an activator which causes a chemical change to occur that results in cured coating while others require heat to cause the chemical reaction to occur. Coatings that require an activator or heat to cure are much more durable than a coating that just relies on the solvent that makes it liquid to evaporate.

Don't cure it per the recommendations and it won't last.
