There is no short supply to products that can be applied to the car. Jman, I see that you are also in Wisconsin, where about are you? I do detailing work on the side when weather permits and would be happy to help you out if you want, and aren't too far away. I actually use ceramic coatings on my cars now since they last so much longer then typical waxes and sealants. I've got 3 years on my Optimum Gloss coat right now and probably need to re do it this spring.
As far as washing goes, I use ONR with a bucket and grit guard. I have 5 edgeless microfibers from the rag company that I use to do the ONR washes. I use one of those pump garden sprayers to "presoak" the car which helps loosen the grime and dirt and the start from the top down. Towel 1 = roof and windows, towel 2 = hood and front fenders, towels 3 and 4 = one for each side of the car, and towel 5 = rear hatch/lift gate. I fold the towels into the fourths and refold to a clean side quite often.
If you are looking for a decent product that can be found quite easily locally, ie Walmart, check out meguairs fast finish. It's a polymer coating that is super easy to apply once the paint is clean. Just spray a bit onto a clean microfiber and wipe onto the car, flip to a dry side of the towel and buff any remaining product off, there won't be much.
If a car isn't coated or I'm not coating it, then for a winter wax I use Collonite 476s wax, it's quite durable and should last thru the winter. In the summer months I use mostly Collonite 845 or Meguairs Ultimate liquid wax because of how easy and fast it is to apply and remove and neither of those stain or leave marks on the black trim.
One thing with modern waxes, is "thin is in" its better to apply 2 very thin coats then one thick coat. This is because most products sold as waxes are actually synthetic polymer sealants and not natural waxes. When I use Meguairs Ultimate liquid wax I actually apply to the entire car before removing most of the time because it allows the product to setup and do it's cross hatching bonding thing with the paint.
If you have other questions just let me know.
