yes that's the right order.
I once did 30 layers of Klasse SG and it was like a candy apple, lasted for months!
but the key is not in waxing but what you do before waxing in other words the prep work that you do before waxing will give your paint 90% of its punch.
1- Wash the car twice at least.
2- Clay every panel of the car until the clay glides smoothly and effortlessly.
If you don't do this the wax job will show flawes.
3-Wash the car after claying, the clay bar may have loosened pollutants and sediments that you don't want to smear across the paint. The worst thing you can do.
***On a black car I would do at least one coat of 3M rubbing Compound(for black cars) to smooth the rough edges of your swirls. This will improve the "daytime" shine 100% If you don't do this the hard edges of your swrils will reflect light and look terrible. I rarely see a black car whose owner bothers to do this.***
4.Klasse ALL in One with a foam applicator applied evenly and never in circles or removed in circles. I do AIO twice since its only used a few times a year.
5-Klasse SG, one drop per panel using a damp MF applicator. Remove using a slightly damp towel. I like to use Sonus Acrylic Spritz, its made from the same ingredients as Klasse SG and will get rid of the very common streaking caused by using more than one drop of SG.Each SG layer has to sit for at least 8 hours. I once did 30 layers over a month.
Once you get to your 7th layer (at least!

) put away the Klasse bottle for six months and get out the S100 and use this once a month.
I use Sonus Carnauba SpritZ after my weekly or biweekly wash. Very important:
Spend a few bucks on
QUALITY towels. I use Sonus Der Wunder polishing towels to remove waxes, they have looped ends and not open 'prickly' ends like most auto store Microfiber towels. And for final buffing of S100 I use a dedicated buffing towel like Meguair's Gold Class.
Other products I really like:
Klasee VLRP for black plastic and vinyl interiors. Makes it look new not Armor ALL!
1Z Rubber and Vinyl for tires, nice deep dark matte finish.
Meguairs' NXT for wheels, last weeks.
1Z Leather to clean seats and Lexol to 'moisten'
Einman Fabric or Woolite for your carpets with the Meguiars Gold Class carpet brush.
