Scratch X - really impressed with it! Used it on a hairline scratch on the clear coat on my Titanium 182 at the weekend. It essentially reduces the clear coat to the same level as the scratch so the scratch is no longer visible.
Be warned it does require a lot of elbow grease and youll also need several (3/4/5 or more applications), but its worth the effort.
Weather dependent my car is getting its first claying, body scrubbing, and NXT Waxing this weekend - not that it has been neglected - but it has not been treated to decent products such as Meguiars before. Hmm we will see.
