Since I plan a larger “processing” of my car in the next time I have one, two questions. which wax is the better from the point of view of durability / service life. Collinite No. 476s (or 915?) or the SN or the SNH (or the SNH seal) of DJ? The last bit of shine is completely irrelevant to me… I only want to have something about the wax and the effort for as long as possible. Effort – benefit should be in a good relationship. I should mention d if I already own the DJ SN but have used it only for small test purposes so far… maybe I could give it up if you tell me that the 476s will last much longer … Would it be advisable, should the Collinite last longer in your opinion, to use the Collinite No. 840 PreWax Cleaner instead of the DJ Limd Prime if I take the 476s or 915 wax? Or will I rather not notice any differences in the service life (positive/negative influence)?
