Chopper gun (sprayed) fibreglass is always inferior to hand laid 'glass.(I found out the hard way)
It's inconsistent in thickness and generally poorer quality.Hold one up to a strong light and you'll see what I mean. eek

Shell out the extra bucks for hand laid,or you'll regret it....
Unless you really want fibreglass,try and source some good originals,they're still out there.
