question about sandblasting

[awsomeaussies]

Anyone know if you need to plug bolt holes when sandblasting? I'm using aluminum oxide to sandblast my swingarm and I don't want to screw anything up. Do I also need to plug where the bearings come out.
Thanks in advance

as long as your under 100 psi then no, it will hurt nothing. when you are done blasting, use an airgun and blow out all the holes
