I will miss the line, and yes it was indeed expensive. When used correctly, there has been nothing easier to use IMO. The gloss was notable, the protection was clear, and the installation/remove was simple. I found durability to be reasonable on the wifes truck which was garaged, although longer protection might have increased others use of it. Spray on, hose down, then used Master Blaster to remove all remaining water. Light wipe with damp towel to remove any waterspots.
To date I have not found any other spray (no wipe) that works like it. All the other streak terribly and needed additional wiping or buffing before they set it. I will miss Permanon and hope that it has additional formula updates, perhaps a pricing re-evaluation, and makes it back to AG.
