Not powerfull enough to do any correction. You'l end up buffing the paintwork slightly.. probably creating swirls rather than getting rid of them.
A Silverline polisher can be had on ebay for about £45. Then after pads and polish its about £80.
Ive got a blue one. Its not excellent, But if your carefull and take your time good correction can be done.
Better off spending more money either to get a professional to do it. Or read a few threads on Detailing World, And then spend the money on some propper kit if you intend to use it.
If you just want a bit of shine.. Get some AG Super Resin Polish from Halfrauds.
