I can't see much wrong with those vapour blaster components personally. I think the best thing with vapour blasting is it doesn't remove any material. Any form of media blastings is going to have an effect of mating surfaces if you are not extremely careful, plus it's possible to leave remnants of media in oil galleries and other nooks and crannies!
The only thing with vapour blasting is as Fenton says, it leaves the cases very "dry". Steve's solution of washing the parts in parafin is a good idea as it's oil based, so will seap into the "pores" of the alloy and offer a little lasting protection. WD40 is too light, and evaporates and dries out quickly. ACF-50 is designed not to dry out for a much longer period of time.
"TYGA Soup" also dries the alloy out and can lead to ozidisation if the parts aren't treated afterwards.
Well used but clean cases are the best though, as the years of 2T mist swirling around them keeps them nice an moist... and we like nice and moist!
