Accroding to CG, they told me Extreme top coat sealant is longer lasting than there magic seal. However i just applied these products and am not sure about longevity but i wouldnt doubt that they are top notch products.
Revive glaze is AWESOME. Especially on black cars. I applied some onto my black prelude and whoo weee...i did a 2x2 section and the area i worked it into was darker and wetter by ALOT. I thought it gave this effect because i didt not wipe it of with a MF, but even after i wiped it off, the darkness and wetness remained.
The carpet cleaner is great too. Spray it on, use a brush, then blot it out and leave it to dry. Similar to folex but i prefer folex because it isnt as foamy as CG.
The leather conditioner is great. It smells like real leather and makes your interior smelling brand new. uhm...not sure but zaino leather conditioner smells the same as CG conditioner. The CG rep told me that they supply the brand Coach with leather conditioner, and the leather conditioner Coach sells i just CG leather conditioner.
