Resolution of sorts - I put my case back to him with exactly what I'd expected and what I wasn't happy with and to be fair he's agreed to a full refund without any argument. It doesn't rectify the issue but at least I'm not out of pocket as well as p***ed off.
I made it very clear that it wasn't acceptable and after that his attitude towards the issue seems to have changed a little. He's apologised and admitted that his view of guitars was different to mine (tools for the job rather than valued items etc.) but admitted that he's learnt a lesson in that not everyone sees it that way and will look to change the way he works to prevent it happening in the future. Time will tell I guess but the eternal optimist in me hopes it's done some good for future customers.
Rather than openly name and shame, if anyone is looking for a
luthier in my area (Leicestershire) or wants to find out more info, feel free to contact me directly and I'll happy discuss the details.
On the topic of repairing, as Rich says, fill or no fill, wet sanding will be needed. It's not that daunting when you've wet sanded your nearly new motor to remove marks and polished it to a perfect shine again
You ought to look at
www.detailingworld.co.uk and see some of the things that are done by the guys there. I've seen posts about brand new cars that have had the entire bodywork wet sanded to remove orange peel. The results were stunning (scary though!)
Cheers,
Carl
