This may be of interest - I have made a right mess of the paint on my
NHB CTR - I addmittedly didn't know what I was doing when it came to cleaning. The thing is covered in swirl marks and scratches, so tonight the car is off to the detailers to get machine polished and returned to its 'blank canvas' state - I'll keep you informed of the progress and results.
The chap has also agreed to give me a quick lesson in proper car care technique so hopefully shouldn't happen to any great extent again. In the meanwhile, watch this space...
