You guys are a cheerful lot aren't you. Reviews and opinion please....cuz some of the stuffs i also never use before...

1. Yes, it'll fit fit the Bosch.
2. If you plan to do one whole car, i would suggest 2 x orange & white, 1 x black. If on budget, one of each colour would do.
3. I haven't tried UP with a cutting pad before. But knowing the type of polish it is, you should be ok with that combo. Just not sure how the outcome would be.
4. You can. But if you car's paint is very soft, you might get a some slight hazing. Better use black la....to be safe.

Errmmm....just to note: you might need Ultimate Compound for that....or maybe a few passes if using UP. So don't give up if you can't remove it in a couple of passes. If you see any improvement, just keep going.....
