Speaking of supercheap I went in today to get some more car wash and found the above. Interesting concept with two reservoirs to induce some protection just from washing. I did read some reviews. Common reports were that the wash component wasn't very good but the Sio2 coating did work. Couldnt find reports on how long it lasted though.
I did not buy it, didn't feel like spending $50+ for some car wash.
