Used the liner on my springs. Didn't know how it rode before hand but it does good now. However, I'm working on a 50 coupe that still has the wrapped springs. It will be interesting to see what it looks like under the wrapping.
Denny, thank you for posting the results. I know there are occasions where some lube may not be a good idea but in generally I've always thought a little dab would help not hurt. We learn each day. As my industrial arts teacher said many years ago, "the biggest room in the world is room for improvement"
I've never forgotten that and try to learn a little something from each thread.....if I could only remember them all?!
