Damn carwash!

Took my car through the carwash as a last minute thing as the weekend had been spent preparing my sons christening so could wash it myself. Wanted it looking clean for the day. The carwash has left some minorish scratches and as thus I require your advice.

I've seen T-Cut used in various jokes around here but basically wondered if this would work?

Also the best technique to use such a product and the way I can keep the surrounding areas looking good.

Thanks folks!
