Aluminum intake manifold restoration/reconditioning

[cheveslakr]

I've cleaned several that are fairly rare and never painted them or blasted them. Mostly just strong detergents and gray scotchbrite then steel wool. The steel wool will provide a bit of sheen, so use with caution. They take on the look more akin to the alum. thermostat housings, more of a dull grey, vs. the silvery look. That, to me anyway, is accurate. No protectant on the eddy, boeshield on the winters manifold.
