I had a bit of a bummer.. ..absolutely no knowledge of the coatings , only had my D3 treated last year and that still looks good..
But the guy who did that wasn't to be reached and I had to choose between silly money [ € 1200 ] or a extremely cheap € 375...
The guy offering the cheap version runs a carwash and is a professional car painter, all the background one could hope for..
The coatings are a sideline for him, he likes to bind customers for the carwash [= frequent] and dent repair [ = big bucks ].
Sadly he didn't do a very good job and now the swirlls show in [or under] the coating. I really don't need another fight as
I have several lawsuits with the local council and tax authorities on my hands.. So I agreed to get the expense covered in
car washing... Better then nothing..
My message is : don't go for the story of the seller. Try to get in touch with previous clients. Recent ánd old...
I will wait now for two years for this coating to wear off and then have it done by the € 1200 guy...
