I've been following this thread, because I too have an 82 300SD with blue leather seats that have really been worn and scuffed. The leather is in good shape and only the dye is shabby. I'm going to try the shadow blue that the original poster used. Now I can also add to this thread. Many years ago I bought a 45' power boat and lived on it for 5 years. The boat had a large salon area with huge areas of vinyl tufted walls that were a gold color. I wanted to change the color to white and asked a fellow square dancer who owned an auto trim shop for advice. He turned me on to SEM products and advised me to follow their directions to the letter especially about prepping the surface with their vinyl prep. I bought quart cans and after carefully cleaning and prepping according to their instructions, I started to brush the paint on in an out of sight corner. I was very disappointed at first, because there were horrible brush marks. I waited for awhile to see if it looked better after it dried. To my amazement the product seemed to flow out as it dried. I soon realized you could put this stuff on with a stick. I did the whole interior, and when I was done, you would swear I had put in a whole new interior. I then decided I wanted to redo the large bolster loungers that actually coverd the access to the engines. I wanted to do a mauve color, but started wondering how the dye would hold up on seating surfaces. Walls were one thing but constant abrasion from party animals. I decided to do it and again carefully cleaned bolsters and used their recommended vinyl prep. I noticed that the prep product left the vinyl tacky to the feel. That must be the secret. At any rate the SEM product wore like iron. We partied on those bolsters for several years without a flake coming off. I highly recommend SEM products.
