I’ve been trying to search the forums on current information protecting finish of new aluminum timing cover, intake and heads. Currently I am investing to me what is a lot of money in aluminum intake, timing cover and heads. My experience in the past has always been that after time starts to pass the aluminum parts get corroded, oxidized or stained and do not not look as nice. With the cost of today’s accessories continuing to increase what are people doing to protect there investment? Powder coat, paint, clear coat, polish? What are the pros and cons of the choices or suggestions? On one had I’d like to show off the natural look of the aluminum but not at a cost of having to remove them later to freshen up later if I can prevent it or comprising the dissipation of Heat of the aluminum components. What are the suggested options?
