Hi!! I work in a bodyshop distrubution company, Carlac but we dont have a branch in Liverpool !!! You may have a local brown brothers or check your local phonebook for your closest .. They will knock you up a 10th of a litre for next to nout and should also give u a touch up kit if not just use a normal touch up brush for now till you get it sorted!! Just take your paint code with you..
Wouldnt care i have loads of flint grey kicking about mine is in getting a full shoot now..
Hope thats of any help!!
