I am currently in the middle of painting my 90 and have bought some new wide wheel arches off eBay but they are made of fibreglass, my question is what primer would you use before painting them thanks.
 
Suspect you'll get differing views around using etch primer and a flex agent on fibreglass

Personally would just try a hi build primer and see how it goes

Main thing is if you sand, to clean thoroughly and finish with a tack cloth to remove all dust
