What should I use to get rid of these scratches/stains?

^^^ you did polish, now wax maybe needed. or more polishing, imo

[heylookitskarl]

this is polishing .. you polished the scratch out is what I meant
Ok sweet thanks, now I understand what you were talking about

so you need to polish some more. Maybe with a different product and technique.
This is one of the frustrating things about paint correction. Usually when you polish you have to keep polishing until the surface is perfectly flat. Hope that clears up what I meant.
Ohhh ok, so next time I'll just repeat the apply and buff out process a few more times and see what happens

Does the compound take some of the polish off in order to level out the surface?
If the answer is yes then would i have to worry about removing all of the polish off the car?

When you are done polishing, the area should be wiped clean with a microfiber. If there is a possibility some polish is left over, you can wipe the area down with 50/50 (rubbing alcohol/water) mix. With the surface truly clean, the compound can do it's job effectively and level the clear.

You can wipe your car down with the 50/50 mix to remove all leftover polish/compound, giving a prepped surface for wax.

Ultimate polish before Ultimate Wax, if you are doing this by hand, your results will be significant better if you use a DA.
