There's no such thing as the propper paint, you don't order it from seat, they'll use one of the top brands, hopefully, DuPont, ppg, standox etc
 
As said earlier the wings might need blending on a colour like that to match the bonnet.More than likely the bodyshop will do a spray out card and offer it upto the bonnet/wings first to compare the paint they have mixed against the original paint
 
Is that's the body shop along the road from seat pulman ? They seem really clued up on seat paints. Was going to get mine done there but bought some super copa alloys instead

Aye that's the one mate, they did the alloys on my first FR and they were spot on

They had 2 brand new Ibiza FRs there when I dropped me diffuser off to be painted
 
Pullman sent me along there when I tried to get the rust sorted under warranty. He knew about colour changes in the metallic fleck between different years.
Really want the whole front end of my car resprayed.
