Auto'N'Industry Spray Paint Supplies, factory 11 / 229 Colchester Rd Kilsyth 03 8761 6710
Bought some gear from here last week and couldn't have asked for better service.
They sell a large range of auto paint and paint prep equipment and all reasonably priced.
I bought some stone guard and the gun to apply it and was given a full run down on how to apply it, preparation required, compressor settings etc.
cheers
Bruce
