Got another two wires blasted and sprayed in primer today.
I also found out what happens if you get half way through sand blasting a wheel and then leave it for three or four days without spraying it - the surface flashes over with a grey powdery coating that's really difficult to shift, even with the 'blaster.
I've really got the hang of the sand blaster now though and I can't wait to get stuck into the chassis and font bulkhead over the next few days.
Will post pics when there's something worth seeing.
