Mercedes GL420 CDi Enhance & Protect After performing a similar detail on the households 997 Turbo a week or two back, I was invited over to do the same to the Wifes Mercedes which is also a daily runner. Having already worked on a GL series Merc, I could already appreciate the sheer size of the things.. I think I quoted last time as big as my house.. heh! Before: After: Roughly 17 hours put in here over the course of two days. My first solo B&B experience, too! (Allowing for a later finish and earlier start as there was travelling involved..) Inspection. You can see the O/S rear quarter looks as though its been through a bush; stood out a mile! As per, the wheels/tyres/arches were worked first. Mix of Meguiars Wheel Brightener, Meguiars APC and AutoSmart Tardis. Various brushes, mitts and tools used.. Next? Sills and shuts. No photos here as I was against the clock. Vehicle given a thorough rinse pre-snowfoam stages. Front-end also received a healthy douse of G101 to soften the kamikaze bug-splats. After the wash stage was complete, AutoSmart Tardis was used to dissolve small tar deposits scattered around the vehicle. And then clayed with Sonus Green/Meguiars Last Touch: Continually being rinsed with the pressure washer to remove residues, and finally sheeted with an open-hose to aid drying. Car = clean. The O/S rear quarter looked a bit of a mess: But other areas didnt appear too bad: Initial Dodo Juice Lime Prime tests were carried out but didnt give the required results. The bonnet suffered quite badly from what appeared to be Limestone marks.. Etched into the paint much like a bird bomb does.. Stepping the combination up to a Green Hex-Logic polishing pad and Menzerna 203s helped things, but, was unable to remove completely!
