Being that durability is my #1 priority, I do love durable products, which explains my adoration for Zaino for so long. So, if it protects my car that is exposed to UV and weather 24/7, then I am all for it. For those of us that don't have garage queens, this product sounds like a winner!
On a side note, let me be the first to ponder that the mysterious formulation is from 4*. Anyone else care to guess?

A free bottle to the winner?
