I used this Radiance on my brother's car which is a 530e in the same colour as your X5 (Black Sapphire). The body was decontaminated last September so I applied the Cloak first, buffed off after 15 minutes, then applied Radiance. A very thin coat is all that's needed. I then let it cure for 20 minutes before being buffed off very easily using one of your Koalas! The yellowy-silver flake
now really shows through the clear coat on this lovely BMW colour. My own car, a red Honda S2000, is currently wearing Trossachs over Titan which I applied last July, it's still going very strong and that car has been very slick since. I'll include Guard in my next order, to see if I can make the finish even glossier before applying Radiance! Absolutely fantastic products.
Just finished waxing my Q3 with this quality winter wax. Went on a dream and came off just as good. Even at 4 degrees. Has left a lovely wet look. Smell like a gentleman's aftershave. Love this product can't wait to use it on darker metalics.
Fantastic wax for the price.
Easy to apply, quick to cure and easy to remove.
Can't ask for more.
