if you can't feel it but its left a sort of white scuff in the lacquer then you can get it out with some light rubbing compound (so light as in next stop is T cut, but t cut won't do it) like G3, halfrauds sell their own light rubbing compound in a yellow tube for £3.
Been using the cheap halfrauds stuff on my volvo 740, and there *was* a dirty great big gouge down near the full length of the nearside, dusted it off, polished it, buffed it, then rubbed it (use quite a lot for this scratch) about 2" either side up and down of scratch, left to dry a bit, then buffed a little more, then drowned it in polish to dilute it off, and then buff to a showroom shine!!!
After literally 10minutes work, I can't feel it and you can only see it if you look at the scratch from below scratch level, either that or pick the car up and hold it to the sun, I am very very impressed,,,,,,,,,
,,,,,SO I did the whole bonnet

, followed by numerous other scratchs and front wings, oh and above the wheelarchs it was practically white, now a high glosss red! etc. Just T cut wax'd the rest of the car, but some time I'm free for a couple of hours I will do the whole car, and then the punto aswell, as it makes a huge difference, not even any swirl marks on it!
