Hi Natalia and welcome to Autopia
Great to know your not far from me. I'm 35 km north of the city out near angle vale
I have friends at mt barker and I have checked the hills region and noticed that there's no one out there with a fixed shop, though some of the mobile boys might get up that way
Well there is actually quite a bit. I do it professionally and just started setting up the best shop in this state at the moment. No one has a shop this big.
There is quite a bit of equipment you would need - orbital polisher, rotary x 2 (to speed things up), carpet extractor (powerful wet vac), levelers, compounds, polishes, buffing pads, microfibre towels and the list goes on and on.
If you decide to get into this and start your own from scratch, I'd be happy to help you with the best place in adelaide to purchase the better products like
menzerna polishes and edge pads and what sites online to get lake country pads and the other top stuff
Trouble with buying a franchise is that you may have to use the products they make or send you and that ain't so good.
