I dont think this is a true polish but its the only thing I have and I want to use it again the right way this time! Last time I used it with a PC and a ccs white pad. I wasnt thinking but would it be better to apply p21s by hand instead?




The P21S CL is like a chemical cleaner, and not really a polish. It's kinda like Klasse AIO. It basically just cleans and prepares the surface for a real protectant to be applied. Klasse AIO protects the surface a little, but mainly it gets the surface ready for Klasse Sealant Glaze, and makes it so that everything bonds good. The P21S CL works pretty much the same way. You would want to apply P21S wax after using the CL.

If you need to remove swirls then first you need to use a real polish, and get out the buffer.
