I've done a few wheels before and a one or two brackets and the like,
but the sand needs to be perfectly dry otherwise the syphon bit that
is dumped in the bag / bucket of sand clogs very easily. The wet sand
gets absolutely everywhere too and is a sod to sweep up.
The cost of dried blasting sand, especially if it is used just once,
rather than recycled in a blast chamber, probably makes it more
economical to get the chassis professionally done. Powder coating or
stove enamelling would make a better job of protecting the chassis
than painting at home would anyway.
Hope this helps
