Car is done. Since I bought 845 for durability first, I don't think I will be disappointed. Easy on, easy off. Don't think I will have hazing but will check again tomorrow. I think I applied it thin enough. Water beads like crazy, I can almost "feel" the protection! As far as shine, has glassy look like I have learned now that it will. I misunderstood about it being a wax, as it's a hybrid sealant/wax. This will be my winter wax on my DD, so no need to top with BFMS. (I have BFWD and BFMS on my classic car and wow!)
What I will question now, is that 845 seems more durable than BFWD. Could 845 not be an all season protectant? Why just use it in the winter? I imagine it would be great in the summer as a LSP and not melt off as fast as a true carnauba. Or you can use in summer and top with a true carnauba. If you use 845, why would you even need BFWD any longer even though I love how easy BFWD is to use.
