I have used Vinylex for the past 15 years with outstanding results. It seems it was recently discontinued unfortunately as I can't find it anywhere. I think I will replace it with 303. Just wondering if there is another exceptional product out there that protect and preserves plastic, vinyl and coated leather seats? I hear Star Brite Vinyl Guard is good. Anyone use it on automotive interiors? I was a pro detailer years ago but have not kept up on newer products. Catch up time! I need something to preserve my old 97 GMC Sierra with TONS of brittle plastic. Want to keep the plastic as pliable as possible and prevent any cracks. Here is a couple pictures of my truck..... Thanks for any input!
