The thing with car paint is that there will be variants of the same colour. I am a paint
Sprayer and what you have to do is check the colour code and if it has variants eg. Lighter, brighter, yellower etc then you have to take the swatches or do spray outs and match them against the car to find the right one.
Also did the just mask the number plate section off and spray that? It is best practice to fade/blend the Base coat in.
I could type the code into my computer and see if it comes up with any variants if you like?
