Here’s what I would do (unabridged) with your stuff for the outside (someone else do the wheels and out side

) Right away, I would recommend you either apply the AIO with foam or a microfiber covered sponge if you have one.
You didn’t get Pinnacle Paint Cleansing Lotion with your Souveran order? (cause it looks like you have the whole Souveran kit, or it might have been cheaper to order it)
Use the wheel cleaner on your wheels. You might have to use a wheel brush, or tooth brush or whatever to get them clean. (I would use AIO on them after or as I am AIOing the body of the car, but you can’t use the same sponge or applicator)
Wash your car, with the PBS. You may want to wash with Dawn before the PBS in order to get rid of some old wax.
Dry the car with your miracle towel (you will also need it to remove the AIO if you only have one, but it’s okay you can use it damp for the AIO). If you only have 1 mt then you will have to either wring it really well and go over a few times or use something else first (like a good quality plush 100% cotton towel) and then finish up with the Miracle Towel.
Wet your applicator and wring it out as much as possible. (foam or possibly the terry, check to see if it scratches with the AIO) Apply 1 coat of the AIO. I like to start with the important parts: hood, roof, trunk. Then do the upper side panels, back/front, and then finally the lower panels. Inspect your applicator/sponge constantly and check to see if it gets contaminated. If this happens either flip it or rinse and wring it.
With AIO use about a nickel size and try to spread it over a large area. I like to use long strokes in the direction of the way air would flow over the car if you were driving it. I wipe in a big “w� and then overlap the wiping slightly. With AIO it’s a cleanser so you can really work it in if you want (as opposed to just laying on a coat).
After you get through the whole car, then take a break, for 20 minutes or so.
You don’t really need to remove the AIO haze, cause there shouldn’t be a lot if applied the correct (small amount).
Go over your car again, following the panel order if you like, and always checking your sponge for contaminants (rinsing and wringing the applicator as necessary). Concentrate extra on the “rough� spots and any visible spots etc.
Take a 20 minute break (or longer) and then buff off the AIO haze. If your MT was still wet from drying your car, wring it out big time! And use it to wipe off the haze. It is better to have a fresh towel to do the final wipe of the haze.
I would then layer on 1 coat of SG (for future reference), every day or so, waiting 20 minutes before buffing and waiting about a day before reapplying, waiting 20 minutes before buffing and waiting about a day before reapplying, etc J
Some use 3 coats of SF back to back, allowing probably an hour in-between coats, and that’s fine too. If at any time your car gets dirty between coats you need to wash (or at least wipe if dusty) You don’t want to apply SG with dirt on your paint (check your sponge it will be the best indicator of how “dusty� your car will be).
Wait a week to apply the Souveran, personally I think you can apply it over just the AIO. Because everyone in my family uses AIO only and it protects their cars for 6 months. They don’t get into all that glaze stuff
Wash your car with the PBS, two bucket method, wipe dry with the MT.
Apply the Souveran one panel at a time and then remove with a soft cloth (mf or cotton) as soon as each panel is finished.
Wash your car weekly, correctly, then dry with the MT making 1 pass, and then making a final pass with the MT and your quick detailer. Do this weekly and apply the Souveran probably tri-weekly and reapply the Klasse possible 6 months from now.
