Topic: Restoring Aluminun intake

[JKWilson]

Jeff I recently "discovered" what produces a pretty nice result. I used fine glass bead with a blasting pressure of approx. 40lbs. I had done some previous blasting with a low pressure and forgot to turn the pressure back up on my booth regulator. The resulting finish is pretty bright (which surprised me after I began!). I had none of the dull flat finish normally seen with higher pressures. I've done about 6 pieces now with the same results.

Tried walnut shells and other things  have not gotten a great results as of yet. Not looking for the bright just blasted look nor the rough surface most blasting produces but instead a semi-smooth darker finish (can brighten up the machined surfaces) you find on new intakes you see out of the box

The finish is the same as a new edelbrock intake manifold.
