I wanna start doing some car detailing and right now I have all meguairs stuff so I might as well just buy meguiars unless if their polish is really that shitty. I go to their site and the store and there's all these different numbers like 83 and 84 and a few others. I know what a glaze is but I don't know what the difference is with their numbers for polishes. They just seem so random. 83 and 84? Is it the abrasiveness? And is there a way to figure out how abrasive they are? I'm open to suggestions of other brands as well. I saw poorboys and was thinking about getting #2.5 and 1 polisher.
