I contacted one of the Melbourne installers (Terrence from www.ozishield.com.au) and he quoted me $700 for the front kit installed, however he doesn't have a workshop and it needs to be done in a covered area, where there is sufficient light and no wind. I also got in touch with ducoscratch.com.au and they recon I can install their kits myself, but judging by what everyone is saying it really needs to be done by somebody who has experience with these kits. Any Melbourne-based people here who had this done? Who would you recommend as an installer?
