I am going to try and repsray the wing on my scala and have found the paint code on here

Ive even picked up an old Spray Gun and Compressor from the Car Boot
So any idea what i do next ?
Does the paint come ready mixed ? or do i have to order paint and thinners ??
Any Idea where I get it from and how much I need and Cost ?
You may get the Idea I havent got a clue what I am doing -You would be right

Cheers
Wayne
