Hi, i am taking my Cinq in for a service soon and am getting some touch ups done on the paintwork. I had the thought of trying to smooth over the bonnet myself, then get it sprayed properly when its taken in for a service. How difficult is it to smooth the bonnet? And how do i do it?! My older brother can weld if thats any help, i cant see it being a hugely difficult job tbh. Also, would the whole bonnet need to be resprayed, or just the area where the badge was? Thanks
