There are good and bad outfits at home and abroard.
If things go wrong in the UK, you speak the same language, you are working within a regulated legal system which you are familiar with and there is a degree of consumer protection and you know where they live!!!!!!!!!!!
Also they are probably not funded by Russian mafia money!!!!
Striking a balance between this and cost saving is the customers choice.
My last engine overhaul was done in the UK, not the cheapest option, but the option I was most comfortable with.
Since then (over 8 years ago) I have had excellent support for the engine with good and friendly advice at the end of the phone.
Probably the worst respray story I have heard is the Cessna that had all it's rivet heads sanded off (in the States). The cost of repair would be immense and I suspect the aircraft was a constructive right off. I saw a Piper Seneca in the UK that had paint stripper sepage on all it's windows requiring a complete replacement set.
If that happened to you would you be able to deal with it in an overseas court?
Caveat Emptor
Just remembered the RAF Wessex that was resprayed at Beccles about 17 years ago, flew to Aldergrove and arrived with 12 feet of paint missing from one side. Primer incompatible with metal surface treatment.
It could be you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
