Aye Ian, it is all in the preparation and the more you can do before handing the parts over, may help reduce the cost. But with hourly rates of £40 - £50, not uncommon among skilled self-employed artisans and paint costs of £40 + per litre, plus thinners, plus laquer, plus rubbing down and drying times, I am not surprised at your estimate for £400.
By the way is this for 'fragile' cellulose' or more robust 'two-pack', the latter being better able to resist the dreaded ethanol, but still be susceptable to attack.
I attach a thread for individual contemplation upon the paint types and their attributes. The degeneration into personal vilification towards the end of the thread!
At one time, if my grey matter is correct,
