DO NOT CONTINUE TO THIS STEP STEP UNTIL YOU ARE SATISFIED WITH THE SWIRL LEVEL OF YOUR PAINT!
5a. Sealant 1-2 coats recommended
Now that your paint is clean and when you are satisfied with the level of scratches (lack of), now you apply a sealant.
--Once you seal and/or top, you can't go back.--
The sealant is there to seal your hard work. The topper is there to protect the sealant, provide more depth and color. At any time after you have applied the sealant and/or topper and you try to use cleaner or polish you have just removed/weakened the the sealant/topper. You can not alternate after you have applied the sealant / topper!
The sealant can be final step, but you do not want to do this until you are happy with the way your paint looks. Does it still have swirls you want to get rid of? Then you need to keep using swirl remover or polish until you are happy. When you are satisfied, then you move on to the sealant and IF you want, a topper.
Keep in mind that you do not "need" an LSP / topper. (5.b) It does provide the extra depth, color, shine and durability, but if you want to or enjoy waxing, you can use a sealant like Zaino Z2 Pro, Four Star Ultimate Paint Protection, Klasse Sealant Glaze over and over (coat after coat).
