Throttle body - vapour blasting

[hunker7]

I'd like to get the throttle body housing vapour blasted, how do I avoid damaging the two roller bearings?

I don't think your be able to even if you put some kind of plug in the hole where the bearing sits the muck will get to the said part. Could you get the bearings out and refit afterwards ?

Can i ask what is the reason for vapor blasting ? How will you protect the surface after the blasting ?
