I know some wont like hearing about it because most of what I've seen looks horrid. How good can it look? Some that I've seen were so well done you could not tell untill you were 2 to 3 feet from the vehicle. If you previously primer before you take it to a paint shop will they strip it and use there own primer? Just looking for inexpensive rust prevention and to not have a car look like a beater. I will only be able to afford so much.
