2 x garden variety water mist type sprays
1 x one way valve (stolen from a mates water injection )
1 x 60cm length of washer hose
1 x T-piece
================================
Stole the rear washer water supply, ran the new length of hose down to the drivers side/back of the front bar, into the one way valve, then into the t-piece which split the water supply to each of the 2 mist-sprays that are screwed in behind the front number plate, facing back towards the cooler.
Dont forget to unplug your rear wiper or it'll sweep a dry back window every time you use the rear washer switch.
Oh, another suggestion would be to NOT be such a damn cheap-ass like me and use switches and stuff... i.e. do it properly.
All up cost about 30c and took 10 minutes.
