how far up the hood does it go
Definitely want to have this done by a competent shop with the latest clear bra technology! It will not harm your paint whatsoever and will greatly help protect it.
I recently had the front end on my Gallardo redone for cosmetic reasons and they had to take off 4 year old clear bra from my hood.
Paint was flawless under it no residue whatsoever and this was clear bra technology from four years ago, its been improved with "self healing" properties and better UV protection.
I had both my ACR's done straight from the factory and so have many others.
I've seen brand new Ferrari's and Lambo's coming off the transporter trucks right to the installer, it's that important.
