Only 2 stockists I know of in the UK, both of whom are out of stock at the moment. I have a shedload of Zerex, but I really want the UV green without having to add my own UV dye which tends to ruin the water.locutus12 said:will 25ml of Valvoline Zerex do 1400ml of deionised water ?
i would prefere the swiftech hydrx but i will be damned if i can find anywhere to buy it from on google. plenty of reviews, but no one seems to be selling it seperatly from full WC kits.
