The other day my Giulia got hit by a small rock on the highway and the rock chipped away a small section of paint. I'm now looking at either getting a 3m clear bra or a ceramic coating. I've heard mixed reviews on both of these. For example I've heard that the clear bra will yellow over time. I'm not sure what people are doing and I am looking for some advice. What do you recommend? And if you live in the Rhode Island area any places you would recommend?
