Thanks chaps
The real success was the airbrush
I tried masking and using an aerosol spray that I had made up first and it was rubbish - had to sand it all back.
With the airbrush I had to thin the paint down and had so much control, I didn’t need to mask so I could blend it perfectly
Other than the tiniest of drips, it’s as close to perfect as I could have wished for
When I scratched the car my eldest son told me I’d never get it right and that I’d have to get it to a professional
When he saw it last night he just scratched his head, shrugged his shoulders and said “did you do that”? And walked off looking puzzled
That’s success
A great result...
