Hi mate,
From experience i would opt for a body shop. Will see much better quality in the repair and paint side of the job!
mobile repair's as such use a type of 'gazibo' with a fan on it and they use iv lamps to cure the paint. Iv lamps dont cure body panels on a 'curve' as such because they only cure flat panels as far as i can remeber (someone correct me?)
in a body shop the stone chips with get filled, primerd, flattened, and then painted an cured in an oven .
my advice would be go for a bodyshop mate an remeber, you get what you pay for!
If you want it to still look good in a fwe years time, bodyshop is the best option, "smart repairs" almost always are visible and even more so over time, fine for tarting up a car to flog on though or as a quick and easy fix.
Smart repairs are Russian roulette at the best of times, especially Chips Away being a franchise, you have no idea what you're going to get.
Painting outside in the elements is just bad all round. Avoid like wild fire.
As mentioned, I have used a mobile paint specialist years back for a simple scratch on the front bumper. I was happy with the outcome, to the naked eye without scrutinising the job the work was nearly flawless. I used Flying Colours but I think they may have disbanded by now.
But with all the info generally being against mobile paint repair I think I'll go with the body shop option.
Though surely someone has had a pleasant experience from using the mobile fellas? Can't be all bad.
cars aren't meant to be painted out doors, if they were car manufactures could save a fair bit of money on floor space
