Two bucket wash if by hand and hose.
Soap- OTC: Meguiars Gold Class is at most auto stores. I prefer Ultima Paint Guard Wash ($12) or Reset by CarPro.
Quick Detailer: Depends a lot on what your last step protection is. Meguairs Quick Detailer is pretty decent overall. I like carpro echo 2 a bunch and that's what I'm using now. I also have and like Finish Kare 425 Extra Slick Finish.
ONR: Double bonus to buying ONR is that they 1) make a rinseless wash and gloss super easy to do with two buckets and no hose. They have an added shine most of the time that boost your sealant as well. 2) You can dilute the mixture to double as a Quick Detailer as well. ONR is one of the best, although I actually preferred McKee's (formerly DP) rinseless. Again, I currently use and love the carpro echo 2.
Microfibers: You can get a pack of 30 of the Kirkland brand ones at Costco or Amazon. Wash and store them in their own container and they will stay free of contamination
Wheels/Tires: I like 303 Tire/Rubber Cleaner and some from McKees. Tire dressing, I have some Mckees Si02 tire protectant currently and also a couple bottles of wolfgang tire sealant. Both work well.
Interior leather/vinyl: I again like 303 leather cleaner/protectant. I also use the 303 aerospace protectant on the weatherstripping, anything rubber.
Windows: Invisible glass aerosol. A bottle of mckee's window coating will last an extremely long time as well and is awesome
Paintwork Cleanser (before putting down the sealant): P21S Paintwork Cleanser.
I do have a Glaze I really used to like that you can put under or over your sealant. Haven't used it in a while, but it was by far the best glaze I had ever tried.
Paint Sealant: For sealants, Menzerna Powerlock and Wolfgang paint sealant are both great and you will have that one bottle for a long time. Extremely easy to use. I also just used Gliss on top of my Cquartz UK and it was a breeze to use. They are touting Gliss as lasting up to 12 months as a stand alone product, but real world results will vary.
Wax: For durablity on my prior black, I liked the Collinite Marquis de Elegance. Was never as high on 827 as others. For a short time topper, Pinnacle Souveran or Wolfgang Fuzion are awesome. But they are pure show waxes.
Meguiars Hyper Dressing is also great on Ramboxes and truck cover.
That is a thumbnail of stuff. I have a ton of other products that are all pretty good to great. Got into detailing and went into the rabbit hold at Autogeek several years ago. One more thing, a Griot's or other quality DA polisher will make applying sealants, preparing for sealants, polishing, etc, a huge time saver and easily accomplish results.
