Not to open a new can of worms, but when I bought my first '69 Road Runner (in October 1970), it had the V21 stripes, and they were in a flat-type black finish. Most, if not all, of the Road Runners I see nowadays have these stripes in gloss black. I purchased that car used, but I'm almost certain the previous owner hadn't changed it. The first time I ever waxed the car, I made the mistake of waxing the stripes. It looked pretty good. That is, until it dried. I taped off and sanded out the original and re-painted it with some rattle-can flat black and it looked great. That's probably why people go with the gloss black? I always thought the flat looked much better.
