Best product for treating old vinyl

Very cool! Mine are in pretty good shape. They were recovered over the original covers, so they are double covered. They did a good job, too.....it's just kinda dated. I would guess the covers are probably at least 25 years old...maybe older. They are gonna "have to do". lol
When I bought the car the green bench seat was completely roached and I couldn't make do with it. I went to the Pick-n-Pull and pulled a couple of low back buckets out of a van and madw do it those for a year. Then I had Big Daddy Don garlits dreams and put a roll bar in and bought some $20 plastic race seats off of Craigslist and then bought to $30 each then seat covers for them and that was very uncomfortable for about 3 years. Then I cut the roll bar out got rid of those seats and put what I thought was a perfect condition gold bench seat in it again even though it was flawless it quickly broke down because I couldn't do anything to condition the vinyl. Made do with that one for a year.. found some buckets a couple years ago at a swap meet and they were pretty much toast as well but they were white Spirit of 76 buckets so I rock them for a year LOL and this last winter finally got them recovered... So I made do with a good six or seven years before I finally ponied up the money... But again someone will else will have to worry about it in 47 years lol...
