Tonneau cover protectant

[mf360]

What does everyone use to protect their tonneau covers?

I am only able to find Blue Magic Cleaner, but it doesn't look shiny afterwards and I have one small crack I'm trying to prevent from spreading.

Thanks,
Mike

I have been using Extang's tonneau protectant... although I have to admit I have not been diligent with it, and have developed some cracking in the cover...
