There is no better F355 I have ever seen than Terry's. I don't care a jot which dealer/specialist works on your car it won't be any better. Terry is proof that DIY'ers do a damn good job.
I hear you. I have bought 6 Ferraris 1 maserati no ppi's and no surprises. I have helped others buy their first Ferrari and we are still friends! So must be OK. I expect a buyer to know what he is looking at. If I was a mechanic for a living I would not even do PPI's except for a very very small number of customers.
Bob I used these two products. The deoxidiser is slightly acidic so removes stubborn ground in stains. Quite easy to use via a stiff brush. The Jet Laq did not seem to do much although it is stated to "protect and enhance metal surfaces" so I used it anyway.
