More so in NZ. I got my last lot from some guy at the supermarket car park. 3 cans for NZ$59.95. The first lot I bought was at the Auckland Men 'n' Motors show for NZ$14.99 a can.
I guess I'll be struggling to find my next lot here in the UK
Most amazing part is how it dissolves the sticky stuff so you don't need to damage your paintwork to get the tank looking immaculate
