Coat the whole thing when installed with ACF50 first , spray it on with a paint spay type of gun and it goes a long way. on the large areas with easy access just wipe everything with a small soaked rag and let it dry then use your chosen wax treatment after a couple of days. It's expensive stuff , ACF50 but applied correctly is real value for money! Originally it was designed to prevent corrosion in aircraft and will really creep into seams and difficult places and it won't wash or wear away, once you've done it, its there for good!
Being of a certain age I had found that I liked Dinitrol the best and was a little skeptical about lanolin/lanoguard as it was described as an annual treatment' however it really does flat to a very nice thin layer and seems to hold and wear well too. I also found over the years that all these treatments really needed an annual refresh to keep their flexibility and self repair ability at peak levels so I would now use lanoguard as a choice on new surfaces. it also allows you visual inspection through thin clear layer when dry! And its eco friendly!
