Brother being in this for 4-5 years and selling detailing products I'll guide you through a proper procedure. You can also contact me on 03004206904
For wheels and tyres:
Clean with Nanoskin firestorm ultra concentrated apc followed by tonyin iron out(on alloy rims). Later you can use same polish on alloy rims as used on body. Coat the tires with Nanoskin hyperdress.
For emblems, chrome and trims:
Clean them with Koch chemie flb to remove all limescale and rust followed by Nanoskin firestorm ultra
For body:
First clean all tight spots with Nanoskin firestorm ultra and detailing brushes
Then wash it with car shampoo
Then use mjjc clay bar with shampoo
I'll recommend you to use a car Polisher if you want really mouth watering results:
1st step: Use Koch chemie h902
2nd step: use Koch chemie f6
3rd step: Apply any wax of your choice like chemical guys butter wet wax
Then you will have a showroom condition car ready
