Are the scratches deep? Rule of thumb is...if you CAN'T feel the scratches by rubbing your finger/ nail across the scratch, the SSR process will work well. If you CAN feel the scratch, and it's down deep, to the metal, it won't do any good. If it is into just the clearcoat, SSR will mask the scratch somewhat, but you will still be able to see it in the right light, angle, etc. Color of the car is also a factor.
The normal charge is $95.00 to do an entire car, scratches on most every body panel. For 3-5 places, $65.00, tax included. It would probably take about an hour.
I'd like to take a look at the scratches in person if they are surface scratches. I live in Bedford, so I can meet you somewhere if needed.
Hope I've answered any questions you might have. If not, you are welcome to give a call.
