Not worked out cost yet. Tried it on the car (which your not legally supposed to) with Rainx one side & this the passenger side. Rainx is good over 50mph ie. don't need wipers but this new stuff works at sort of walking speed.
PS. the guy that developed it IS the guy that founded Rainx.
OK I would be interested too, have tried RainX but the effect only seemed to last a couple of months, if this is better then and price isn't ridiculous then I would be interested.
