Black is the worst color, shows every swirl.
I have always used Maguireās 3-part wax system with good results, but I hate all the work and detailing the white residue that gets into every crack and on the trim.
For the Lethbridge car show I decided to try the new Turtle Wax "ICE", this is a clear polymer finish, well all I can say is it is amazing. Application and polishing is easy, no visible swirls remain, I even did the trim and bumpers. The only thing I am not sure of is how long the shine lasts, but it is so easy to use you could apply it with every wash
