EdwardL,
mate you cant get it locally I tried about a year ago. there are just as good polymer sealers over here in Aussi that you could use. go to Welcome to Waxit.com.au - Australia's home of Premium Car Care Products, brands = Pinnacle, Swissvax, Zaino, Wolfgang, Poorboys, Klasse and have a look at what Dave has to offer, you wont be disappointed.

Bozz.
