So you think meguiars removal X would work ?
Two things mate: (don't take this the wrong way)
1. How can you expect people to help when there are no pictures/details of what you are trying to correct?
2. My opinion is that you should really be posting this in the detailing section of this forum as you might get a quicker response (only though, if you actually provide details of the scratch).
People will help you, but you need to give them something to help you with.
I know you know this, but more aimed at others considering this - wet sanding is a bit of a last resort for scratches, orange peel, stone chip repair etc. You will remove a heck of a lot of the top layer, relative to polishing, using this method.
