    I have an aluminum intake I want to restore to new finish. I found 80 grit glass bead. My question is will blasting it with that work.

    What does the intake manifold fit? If it is exposed to the oil like SBC then I don't like to use a bead blaster on it. You'll never get all the grit off the surface, and hot oil will do a great job of scrubbing it off into your crankcase.

    Fresh glass beads do a great job cleaning aluminum. I usually get a batch of parts together and thoroughly empty out the cabinet then fill with new media. Unbroken clean glass beads leave a bright mini shot peened finish. Dirty used media will leave a rougher surface with all kinds of crud and rust embedded in the part. Always wash parts well before use and try to remove shields under intakes before blasting as it can't be completely flushed out after.

    Not having a blaster, and having an intake stained with old gas from a gasket leak, I tried NAPA "Aluminum Brightener". With a garden hose and a collection of scrub brushes, it came out pretty good. Doesn't do much for the oily dirt that collects in the nooks and crannies, but some Super Clean and more scrubbing took care of that.

    You don't need to tape off machined surfaces...unless you want them to continue to look like machined surfaces. If you do, then, it would be a good idea.

    Yep^. Maybe tape over the exhaust crossover passage with duct tape. Lots of sticky crud can collect in there that would hold grit and soap might not be able to knock it loose.
