When you get the application right, the finish is no better/worse than most production cars and only requires a light flat to improve the overall finish. However, like spraying, runs and putting the paint on too thick can give you a lot more work to do and dampen enthusiasm. That said, for many, the final result without flatting is acceptable and either way it tidies up even the scruffiest T25 without the need for it to sit there. masked up, doors off and all trim removed, while you get the spray gun on it. I don't know about the rest of you but I wouldn't have the time or budget to spray - too busy driving it
Mind you, I'm planning on a complete flat next year and two fresh coats as mine was done 4 years ago and shows all the usual signs of scrapes along hedges and general chips. The time that has elapsed has also helped me identify areas that could do with new panels or more effort on my part. I'm also planning to paint the bottom half Tardis blue as I saw a similar paint scheme on a narrowboat and it looked the dogs.
Good to see this thread rolling on. I must have saved the nation millions....
