You know,,,, you are absolutely correct. The product I used was the STP I bought at Pep Boys. I got my STD in Tiajuana, Mexico. Just kidding,,,, I was a "Good Boy" [][][]ORIGINAL: logueb
What I remember back in the day was STP. It's uncanny how similar the STD and STP lettering is. When I was a teen you had to have STP stickers on the side windows of your ride. STP was sponsor of Richard Petty. Ahhh back in the day.
