Well naturally that's what your meant to do and most reputable places do. A lot of individual and single shop mechanics will too obviously but there's plenty of cowboys.
I can half name a place as I don't wish to expose personal information, it's in Sunderland and they specialise in write off's and maintaining cars for taxi use (rented out to taxi companies)
They go absolutely mental with 'windy guns' and myself and grandfather could never get the nuts off (Grandparents owned a firm) The reason I'd rather not name is because farting around with windy guns wasn't the only thing they were useless at. 'Fixing' write off's and selling them

Depends if you can name the vehicle line up, AFAIK there were only 4 line vehicles whilst I was present, Note, Juke, Leaf and Qashqai.
Being completely honest, I never loosened one there without the windy gun so I couldn't tell you what they're like to take off manually, employees were just told a woman should be able to remove it. It should be their fault though if they can't be removed, everything in their op sheet has to be followed unconditionally by all employees. At the time I assumed someone as reputable as that knew exactly what they were doing. Then there's the opposite side of Mr K's point, not being able to take your wheel off without a trip to the mechanics? or your wheel just falling off whilst driving.
''There's a reason it's done this way'' That's what you're told if you question it.. without ever hearing that reason
For reference if possible of course (Nissan specify between 75ft/lb to 90ft/lb for most vehicles) what would you consider optimal? using either your own opinion or another manufacturers.
