I recently had my car at the body shop and the guy told me that it's bad to use anything that contains silicone on the paint because it prevents the paint from breathing and as the car gets older the paint will become dull.

I use Mezerna FMJ but the bottle does say what's in it.

Does anybody know if it contains silicone and the same question for zaino.

Thanks

 

From my understanding, FMJ is a water based polymer and does not contain silicones. Not sure about Zaino though.
