Corrosion of supercharger and other engine parts on SuperCuda

I believe it is in the interest of the public to know what they may be getting themselves into. Black Pearl Master Detailers have a good reputation in the automotive industry for detailing vehicles to look better than ever before. Unfortunately, after detailing my supercharged 1969 Plymouth Barracuda named the SuperCuda, a vehicle valued over R2 million, they caused massive corrosion of all the brand new parts in the engine bay. This has set me back another 200k and delayed the completion of this vehicle by another month. They completely deny the fact that the chemical corrosion was caused by their doing, however they are the only people that used chemicals on the parts in the engine bay - brand new metal will not spontaneously corrode by itself. Unfortunately, I absolutely do not recommend taking your vehicles there unless you only want the body of your vehicle, ie. the outer shell, to be detailed. This issue was taken up with management (Werner) and he completely denied any accountability or responsibility. My advice is to steer clear of this company and find someone else for the job.
