Linex? to protect lower spoiler?

[2011altima]

have the prokit (1/1.4" drops) and the lower front (spoiler) has quite a few scrapes already ... i try to be carefull! the guy @ Linex (local shop) said it would adhere fine and protect big time. also, w/a 5 year warranty.
Anyone have any comments/suggestions??
Thanks to all!

I feel your pain. Last fall I had to sand, prep, and paint my bumber since its been beat to hell over the years and I've debated having my whole front bumper cover and side sills LineX'd to match. My mother has her bumper covers (front and rear), sills, and lower panels on her Saab done in silver to match her car. Obviously it doesn't match perfectly due to the texture but you could hit it with a hammer and you'd never know it.
