I actually used the generalized term "acid wash" and actually don't know if that's what they used. For example, the Iron-X product is technically advertised as not being an acid based product but will do the job in most cases. The detailer used it and a Finish Kare product on the Evoques he cleaned. I thought those pictures with the purple reaction in the detailing link I posted were interesting. Here's a product description for Iron-X:

The Finish Kare SIRR bottle says 'acid based cleaner' in the detailer's picture. As I recall, the Ford TSB talked as if they used an acid and stipulated that they had to measure the paint thickness and if it got below some threshold they just had to repaint the bodypart. Some of the warnings are to NOT get the solution on bare metal as it will attack it, but that's what you want it to do to the metal particulate caught in your paint. Here's a link to a Finish Kare SIRR description. I don't know what the Ford folks used:

The original thought my dealer's bodyshop had when they looked at my Evoque was that they would buff the particulate out which would ultimately remove some of the car's paint until they got it all out. That sounded too aggressive so I started looking for and luckily found a few things including that detailer's description which I shared with my service manager.
I had to do a search on the Tardis you posted earlier and I have a really bad aphid secretion 'honeydew' thing going on in my driveway right now due to trees and I'm not looking forward to cleaning it off of my truck. That might just be something to try. Thanks.
