I've recently used "Solartint" here in NSW. They have branches in Vic at Berwick, Coburg, Dandenong and Essendon. The local franchisee did a great job replacing the years-old "past-the-use-by-date" films on my MX5. They offer a range of tints and prices, depending on what you want or need. Note that here in NSW there are legal limits on the degree of tint allowed on certain windows. ( Apologies - the logo didn't copy across too well )
