From Collinite:
1. No.476s – most durable protection/weather defense. Most elbow grease required during application.
2. No. 915- 2nd most durable and slightly easier than the 476s to apply/remove. No. 915 lends our warmest shine to dark tones like navy and black due to its highest concentration of rare carnauba.
3. No. 845- easiest of the 3 to apply/remove with slightly less durability than the No. 915.
I love your threads and keep reading over them to learn more stuff every time but would be interested to hear if you could tell or rate their UV protection ability ? I have seen that FK1000 is suppose to have great UV protection but you have rated its protection slightly under 845, so it would be nice to see if one of the collinite waxes has the same or better UV protection, since they may have better overall protection as well.
