its a tad on the expensive side but not much , £250 is a decent price to get your bonnet done ,
even thought it just the first 1/4 that need done , the hole bonnet will prolly end up getting done as its quite hard to blend metalic paint , so they fade it in , and then laquar the hole bonnet
for £300 i would be expecting an exact colour match with no inperfections
and if its throguth the books then you can always turn it down if your not happy with it!
