Years ago i had fitted a big rear spoiler for my mazda from pow-r.co.uk(never again from there, grr!! ) that was fibre glass and must say the quality was bad, cracks started to appear even when had it repaired, it looked good tho along with alot of stuff & that lagana bumper you want but close up, no no unless you spend long time on preparation that will make it look better finish when it comes to painting it, you can be careful however some others out there wont be so kind say in a car park or a tight space. only fibre glass item i get is a bumper spoiler for an OEM bumper
