I Have Had Mine For At Least 6 Months And They Still Look New But I Made Sure No To Over Tighten The Bolts That Secure The Mount To The Windshield, If You Seperate The Coating From The Metal And Water Gets In, It's All Downhill From There.

 

I didn't. Only for the simple fact of this. I paid $29. for the mounts itself and if I need to repaint it or the windshield bracket then it wont cost much. Prolly would not hurt to put a coat of rustoleum on the backside though if thats what's worryin ya.
