I use the S100 products and a low pressure washer at the carwash, but I am having problems with spotting, I do follow the instructions on the spray can, but still, the spots. I am also a new bike owner and would appreciate any tips and/or products that you use to make things look good and maybe even cut out a little bit of the work. I must say that the S100 wheel cleaner is great at getting off the brake dust though.
