Wasn't sure what forum to post this in so I'm starting here. I have a '78 Triumph that hasn't seen the rode in almost 30 years. It's original single stage white paint. It appears sometime over past couple years while it was being worked the rad cap or hose gave way and shot drops of all water and anti-freeze all the way to the back of the car which didn't get cleaned properly. It has what looks like faded brown dots all over the place. What is my best option for getting these out? I have a usable buffer that I normally use for just waxing my other car. Can someone suggest a few ways to get this cleaned up? I know 40 yo paint is never going to be perfect, but I would like to keep it for awhile longer since this care only has 24k miles on it still.
