funny!Just use any good vinyl dressing. I have heard people say that ArmorAll causes shrinkage. I can't say it does, I have used it for many years, on many cars, no problem.
But it does cause for slippery seats when applied if you have vinyl buckets. Found that out the hard way when I was a young buck. Hit the brakes hard while driving my sports car and nearly slid right off the seat. LOL
