The Mequires 3 Step consists of a cleaner, polish & wax.
The cleaner is ideal for prepping the paint after a wash or clay, applied like polish & buffed to a shine. Polish applied as per usual & same with the wax.
Not a bad starter set up & reasonable price, BUT the wax isn't great, it's not the easiest to buff off & doesn't last long, so I'd suggest either a second coat of wax, tech 2.0 or similar or dropping the 3 stage wax althogether.
Alternatively just use a better polish/was combo from the start!
