Hello, since I’m about to get my new MCV I’ve thought about whether it might make sense to treat it with corrosion protection. Who doesn’t know the stuff: It’s corrosion protection grease/wax that is introduced in hot state into the cavities like thresholdrs. The very good effect has already been confirmed by several professional journals. I would be interested to know who has already had experiences or whether the whole makes sense at all. or is necessary due to the already existing factory corrosion protection.
