I bought the kit, but I used the sealant on my VW MK5 .:R32 with machine for the most part and did use the kit applicators for tough to get to spots. The formula is easy to apply either way. The shine is instant, easy to wipe of after hazing up, too. It was warm when I sealed, so hazing is very quick in high temps in the garage. I used finishing polish first, and even though the car is nearly 10 years old, the paint looks fantastic with this combo. The car is my daily driver, and I will update on longevity of the protection. But boy does the paint feel slippery! Microfiber cloths definitely slip off the surface. This is a fast way to seal paint.
