Sand Blasting

[ssbrewskyaz]

The key to blasting engine parts i.e. intake manifolds, tune port runners etc. is the after cleaning. Pressure to clean the actual part depends obviously on the media being used. I would never use sand on aluminum. That's just me. Glass beads probably produce the least porous results with the most natural finish. AO works well however it produces a more porous result than glass.

THE SINGLE MOST IMPORTANT STEP IN THE BLASTING PROCESS REGARDLESS OF THE MEDIA BEING USED IS THE CLEANING THAT TAKES PLACE ONCE THE BLASTER IS PUT AWAY. It is imperative to blow the parts out until you're overly sure that all the media has been displaced and removed, and then blow them out some more.

Media of any kind or degree sucked into the motor through the fuel system will ultimately find its way to the oil and eventually the bearings. ooops. ...SWB...
