I`m with Kev on this one big time.
if the guys wants to do it for 900ish quid then thats fine but i know plenty of proper bodyshops that would take a shit load more than that.
prep is important but the painter still has to have the skills to get it on there right.
i`ve done the 500 quid car resprays and at that price they aint worth doing and the customer get shitty about it cos it aint factory fresh
fuck off and try it yourself then see if youd be happy to only see 500 quid is what i told one bloke

that actual job was nice as well
