This weekend was my first time using this RaggTopp cleaner, protector and brush kit. The process is simple enough but it takes time.On Friday I washed the top of my car. First I used a vacuum cleaner to remove anything on the top, then I applied water with the hose, after that, I used the cleaner and the brush. The brush worked very well, I used it in circular and small line motions stroking first in one direction, then at a 90 degree agnel. The brush only lost about 2-5 bristles in the whole top. Once I finished applying the cleaner and had scrubbed the hole top, I applied plenty of water to get the cleaner out. After that, I used the two included microfiber cloths to dry the top. After this, I let it dry overnight.On Saturday morning, I checked to confirm the top was dry, I then covered the whole car except the top with plastic, this is not really necessary per the instructions, but seems like the best way to go to ensure you do not miss cleaning any over spray from the paint and plastic. Once the car was covered, I used a lint roller to remove any additional stuff from the top. Then I applied the RaggTopp protector, first covering the whole top in one direction. I waited 20 minutes and applied a second coat at a 90 degree angle. Finally I had to leave and came back a couple of hours later and applied a third coat in a diagonal direction.While I have not used one of the other brushes made out of horse hair, it seems that everyone complaints those loose too many bristles. The brush on it’s own costs over $25, so if you are out of the cleaner and protector and hate your current brush, this is a great kit to purchase for the price.
