Natty blue is for dark cars, not white cars, they have a light colour version.
Victoria wax is always a good one, Collinite is very durable but doesn't have as much shine. which is why I suspect Nikku goes over with Victoria.
Klass sealant is also better for a protectant. I'm still trying to use up my Natty's white, which has been good to me, quite a long lasting carnuba wax. I might try dodo juice or victoria next.
