A good friend works in a glass fitting workshop here in canberra and i help out there a lot. He actually does try and at least contain any rust in the sills. O'Briens... Well I had a bad experience there and now that I know more about it, they are a pack of lying pricks (in my own personal opinion). They go around telling people their staff are all highly trained and that they use the best products out, well they use the same stuff as anyone else because there is very limited choice in Australia and their staff are no more trained than you and me when they start. They then go and mark up their prices based on these lies and when you return to them with a problem, they make it out like it was your fault. I know one company that wont ever get my money again...

Guys in Canberra, seriously, if you need any glass go to Aussie windscreens in Phillip and see Chris, they always honour their work and its the same products as anyone else for a lot cheaper. Andie can also come to you in the van.
