Spent my birthday today trying to restore some life in the paint of my 1974 BMW 2002. The last 35 years haven't been kind to the original paint (or bodywork, for that matter) but it never hurts to try. With old and faded paint, you'll never get it back to showroom new (no matter what the ads promise), but with the right goop and a lot of elbow grease you can achieve a 20-20 paint job.
What's that? Paint that looks good 20 feet away on a car going by at 20 miles an hour.
Here's about 20 feet away standing still - what do you think?
