Hello again. You guys will know the best way to do this I'm sure:). I have removed the kick plates (aluminum with Datsun stamped on them) from the rocker panels. I have washed them with soap and fine steel wool. They are coming clean but still need help. Also I have not been able to get the little grooves cleaned. I have tried a buffing wheel on my dremel and that just left a black streak. What is the best way to refurbish this part??
