'Depends on how you do it, though I have no personal experience. If you use the liquid souveran it has a tendency to remove the collinite layer, not sure on the spray wax variant. You can sort through several forums here collinite and souveran for people\'s experiences using the products.'
I did my wife's dark blue Honda van in 845, then topped it a few weeks later with Souveran and it really made a difference. So, yes it can be done with positive results!
