There are a gaggle of users who love it. Wurth Cockpit Spray - ditto above. Wurth people don't like Sonax and vice versa. All type of high gloss shine to the vinyl. I personally don't like this type of finish.
Some people do, so feel comfortable using it.
All of the above products do not contain raw silicone oil. I hope that the above has shed some light on the subject leather and vinyl care. If there are any questions, please do not hesitate to call or write.
