Anyone out there know the correct grade of glass beads to blast 1) crankcase covers/hubs 2) Cylinder heads / barrels (cast finish). The parts were all painted silver as standard so the surface needs to be correct to take paint, not polished. I will be using dry blaster cabinet we recently bought at work and we have a 'massive' compressor linked to it, so no probs with air supply.
I have been offered two grades out of the many variants the supplier sells, as samples of my choice, just need to establish which ones to try out.
Cheers ....Ash
