“A terrific product that's so simple to use. Though you can use dose in a bucket for a contact wash I find it best mixed in 250ml of water in a snow foam lance and sprayed all over a wet car after its wash. No need to let it sit, just jet it all off and be amazed at the water behavior, beading and sheeting. Better, it leaves a stunning gloss that will last for a good 4-8 weeks. Just use it once a month with a normal wash in between.”
