Looking to pull the trigger on a water filter but just looking for some questions to be answered beforehand.
Ive seen the Race Glaze version mentioned in a few posts. Is this still the one to go for?
Also it comes in a few sizes, 7l, 14l & 25l. Obviously the bigger size the longer it will last but is there an optimum size to go for?
I suppose it depends on how many typical washes you can get out of each?
Anyone know roughly how many washes from the 7l size, filling both buckets up with it then hosing the car at the end?
Cheers.
