Edelbrock Polished Manifolds?

All luster, on all parts will go away if they are not taken care of...regardless of the brand. you have a few choices:

1) Polish the intake once-twice a week

2) Clear it with ZOOP Seal (preferred)

3) Have it powdercoated clear. If you have it coated, it will dull a little bit, but it will make the intake look as if it is 'wet' all the time. (i dont like using clear powdercoat on a polished item) - it burns really easily when curing.

Polished manifolds

I have polished E'brock manifold and water pump on my 289, and have had no problems as yet with dulling of the finish. I do keep 'em clean, mind.
