#21 sealant is easy to apply and remove. I used a random orbital polisher on one car to apply and remove, and the edges by hand. Second car was done all by hand. Product leaves a hard, smooth finish. Almost all swirl marks were concealed, and a second coat may remove them all completely. Circular rubbing of the surface with a microfiber cloth after a few days left no swirl marks. Very happy with the product. Waiting to see how long the finish will remain.
Pros:Ease of application and removal.
Hard, smooth finish.
Very little product used to seal car.
Cons:A little pricey at $25, but comparable to what other manufacturers are charging currently.
