I used that stuff so long a go I can’t remember too much about it. I bought a used Chevy Corvair which I restored and gave to my (then girl friend) wife. I used the TR-3 to restore the faded baby blue paint. It did a nice job as I recall but it did not seem to last very long. Of course this was back in the early 70’s (72 or 73) and I have not used it since then. :nixweiss
