Do you think Por15 is a good idea? Or will work? It says it can withstand temps of up to 700F. I doubt the engine irons will ever get that hot. You will have other issues than paint if you can get your engine irons up to 700F.



Or... should I stick with engine enamel found at the local parts store? Honestly I would rather avoid aerosols right now as I don't want to go paint in the freezing cold garage where paint wont dry. And I don't want to spray spray paint inside the house.

 

Regular enamel works fine. A good brand like Rustoleum is what I use. Clean the irons at the car wash with high pressure soapy water and then wrinse. Take some paper towels with you and some WD-40. Dry the irons and then spry some WD-40 0n a towel and wipe the machined surfaces, so they don't rust.



Buy a cheap trim brush. Angle cut fine fiber.



Shake the spraycans of whatever color. at least as long as suggested on the can. Turn them upside down with the nozzel removed. Let them sit for a few hours. Using a finishing nail and a hammer, punch a hole in the bottom of the cans. Wear eye protection. Set the can upright in a jar or can big enough to contain all of the paint and with a screw on lid. Punch a hole in the top of the can. Lift the can and allow the paint to drain into the jar. Discard the spraycans.



Paint the irons with at least one coat of primer from the same brand as the finish paint and once that has dried completely, three coats of color paint, leaving the longest time between coats allowed by the instructions on the spraycans. Put the last coat on heavy to get the best gloss. Let the irons sit a few days without handling them for a good hard finish.



I like Royal Blue.

DONT paint in the house thats how you lose brain cells lol that cant be healthy

 

I have ordered engine enamel in cans and sprayed it with a spray gun, you could do the same and just brush it on if you did not want to let the pressure out of the cans.

 

r/c car trick. if you're using spray paint, put the cans in warm water for a while, the heat makes the paint come out with better atomisation
