I will be painting a 1967 Mustang in the near future, the car does not look bad to begin with but he wants it to be a very good job with a slick finish. Should I strip to bare metal and start from there or sand and respray over what is there? I am planning on 3 coats Euro 5000 let it sit a few weeks then sand with 800 and reclear with 4-5 coats of Universal. Any help and comments are greatly appreciated. Barry recommended me to use both clears on a project several years ago and it turned out great.
