motor painting

hey guys, Im about to take my 350 out of what its in to do some customizing. I am painting the vehicle with a urethane paint and I heard that urethane is strong enough to stand up to engine heat, and i can spray the motor with it,.. is this true?? and if it is, how would I go about doing this? it has some old high heat spray can paint on it now. If i get all the paint off with a wire weel, can I just spray paint and clear and call it good? or will i have to do like the vehicle and spray prime first and all that good stuff. please let me know. Thanks.

I would use an epoxy first then paint it. It has been done and works fine. Engine paint is made to go over bare metal but top coats like base clear are not.

Like he says, Bare metal. Cleaning with a wire wheel will not be sufficient enough to get all oil, grease, and dirt off the engine. If you want the paint to last, the engine or parts will have to be stripped down totally with no residue.
If you don't, the engine paint will start flaking off in a few months.

i can get it down to bare metal. I got media, sand and bead blasters. I gotta tear the engine down anyway so it wont be any problem to blast it. I would just like the motor to be the same color as the vehicle and dont want it to flake off and start cracking off after just a few months. so if yall could give me some info on what to do and what to use after i get it to metal it would be greatly appreciated. Thanks.
