I am not experienced with Poorboy's products but I would suspect that Meguiars #80 Speed Glaze is somewhat more abrasive or equal to that of Poorboy's SSR1. I do know that both products give out a stellar shine if used properly,,,,,,,98
PB SSR1 is not a glaze its a very light cut to almost polish swril remover....its designed to be used after cutting heavy swrils with the likes of SSR2.5. It can also be used as a frist step product if your paint is not in that bad a shape, I do it with mine all the time with this product as a frist step.
