urethane vs. fiberglass bodykits.
i dont know exactly what everyone believe urethane is better. i'll explain why fiberglass is better with 3 reasons.
first, to paint urethane they first have to prime is with an glue like substance that makes the paint stick better, BUT still, its a lot harder to paint urethane than fiberglass. urethane also takes much more time to prep.
second, when you bump urethane into something it will deform and the paint chips off very easy, and when you goto re-paint it, often it is very hard to make look good again because paint wont stick. when you break fiberglass you can just bondo and shureglass it back in shape and prime and paint it up.
and third, when you goto fit fiberglass its almost a perfect fit, and if not, a professional can prep it to fit perfect, but with urethane the fit you get when its made is the fit you get when you install it, bar none.
just my 2 cents...
