Leather Protector Does Work!
I am not one for leather upholstery appearing even a little shiny. Reaching that elusive matt finish may be partly due to a combination of Valet Pros's Leather Soap followed by this Protector. Both products economical in their use and easy. Audi S5, 18 months old seats, trim and dashboard came up with a pleasing even result. BMW 5 series seven years old (had lots of neglect) came up better than expected. The Protector is 'thinner' in appearance than other protectors/conditioners and quickly absorbed. This also means it is easier to apply to leather seats which have holes punched in some panels i.e. Mercedes, Bentley etc with less chance of 'clogging'. Smell wise it is moderately chemically but not unpleasant, an alternative to the other products that replicate the 'original smell of leather'. On the dye transfer issue Provalet Leather Protector so far works though I am not expecting it to last for longer than 3 months on a daily driven car.
