Girlfriend's 14 year old Subaru had received a car wash per year before I met her about a year and a half ago. I have washed it about 6 times in that period and today decided to throw some NuFinish on it. After a car wash it just looked dull. NuFinish is cheap and easy to use and I had a somewhat full bottle sitting around. What a difference! I mean, still looks dinged and danged and scratched from all the parking lot abuse and such, but it actually shines through the scratches. I know there are better things to use, but for 30 minutes of elbow grease on an old car I felt bad for...are there better things to use?!?
