So I got 2 window repellents from the last supercheap auto deal, it's still quite cheap at the moment.
They sent 2 RainX window additives by mistake.
I went back and switched it and got a $5 voucher for the inconvenience caused.
Was wondering from people's experience which one do they prefer?
The repellent is the main product. Each application of the repellent lasts about 3 months. The additive is more a top-up prolonging the application. Americans feel a bit suspicious of the additive clogging up the wiper spray but I don't think that is an issue in Australia's climate.
