a) find a set of rims to run around with for 2-3days.
b) drop rims off (no tyres) to thomastown sand blasting (ur website is the correct place)
c) pick rims up after about 3-4hours usually or ask them to have the rims taken to powder coater
d) drop rims at northern powdercoating, wrong place u got on the link, they are about 15 places further down commercial drive, 2 secs from thomo sand blasting.
e) pick up rims from powdercoat next day and put tyres on. (if sand blaster gave it to powder coat then pick up will be from sand blaster so u can pay him)
just a quick thing too, any centres caps will need to be removed too, sand blasting will destroy anything that isnt metal. at the same time the powder coating place will ggive u a can of touch up for centre caps when u get ur rims, if its one of their colours. gloss black would be.
