Not sure what you are looking for in terms of recommendations? Just which products to use?
I use the exact same process when detailing cars in the Winter as I do in the Summer with the exception of the washing. I will use ONR with warm water in the buckets (power wash at coin op first if necessary). I work in my garage where it stays above 40 degrees and have not noticed any products working differently. I store all of my products in the house though, so they are not constantly exposed to the temps - only when I am using them.
You should not have to use any particular product just because it is cold outside, however the time it takes for products like sealant and wax to dry on the surface may be affected by the temps. Just pay attention to how your products are reacting and adjust your process accordingly.
