Engine Bay color help

Whatever you are going to spray be sure the engine bay is really CLEAN and well sanded before you start spraying. Otherwise it will peel and look like that photo of the purple engine bay with red paint showing where it did not stick. I used a engine steamer instead of a pressure washer because mine was soooo greasy. Comet and a red scotch brite pad gets in all those corners. Be sure to rinse the comet/cleaner completely off before it dries. Any bare metal spots need an acid etch primer which you can get in spray can form. I am not a big fan of spray cans for the color esp if it's a metallic color you are using. Rattle cans are ok for solid colors but if the car is worth pulling the engine to do the work you may as well do a top notch job.
