I'm sure this has been asked before, but is there a product that actually works and lasts to protect the vinyl panels on my Avalanche? I have used several products, such as Armadillo Tuff, Adam's SVRT, and Collinite 855. None have lasted more than a few weeks. There has to be something on the market that will protect and last longer. Any Suggestions?

 

Try using 303 protectant. I've been using this product for years, and it really protects the interior and exterior pieces from fading and cracking.
