Sandblasting an engine for the first time

[jheatherton]

Hey guys, i'm about to build up an 81 250R engine for the first time, looking for some info on what is best to use to blast the engine parts with, i have a bag of
walnut shells that i used to blast some other aluminum with and it took forever even at a high pressure and i test blasted an old aluminum engine part with recycled glass which seemed to leave the aluminum very course feeling and i'm not sure if that is the right way to go, i do plan on primeing and painting the engine myself with high temp primer and engine enamel..any help on the subject would be great.

Thanks Jamie
