Sandblasting intake manifold, how should I coat it?

[Z32]

Hey guys, yesterday I ripped my stock intake manifold off and I need to clean it up because it's all dirty. Well today I'm gonna take it to work and sandblast it. Is there any special coating to preserve the sandblasting look? Or what should I do?

You can just coat it with some matte clear or satin finish clear from wal-mart.

It's aluminum, so coatings are kind of redundant if you can just keep it clean.

When sandblasting the intake manifold do I have to worry about warping the flange?

 

[curt-s]

Warp, no. However I would cover it from overspray. What kind of media are you using? It is aluminium so I would not use coarse grit otherwise it will pit and dust, grime, dirt, oil vapour, all that good stuff be very difficult to clean off once instlled.
