I think so yeah, their glaze come in two sorts, white diamond which is for white/silver cars, then black hole which is for darker coloured cars, I have used white diamond on my silver car with amazing results, not used the black hole stuff but if its anything like the white diamond then its really good.
But the Autoglym super resin polish is excellent value for money, its like £8 for 500ml.
The thing is you'll never get people to agree on cleaning products, especially waxes/glazes/polishes. Ask Juicy Jen aswell because she'll be able to direct you to products more suitable to your car colour.
