Parts back from aquablaster and now high temp painted, things are coming along 

That looks like very neat and tidy work! Is the aquablasting a very expensive process?

Both crankcase halves + both outer cases + barrel + head just under £200

It's time based so the cost depends on how much preparation the operator has to do. If you de-grease and remove paint, silicone, gaskets etc it will save paying someone else to do it.

The bloke who does mine cleans external surfaces with bead blast to remove corrosion and ingrained dirt before the vapour blast, which also saves time.

I use bead blast if I am going to paint something. The paint sticks better and it costs less. I use vapour blast for things that are going to be left bare like wheel rims, fork yokes and fork sliders
