It is a bit of an odd idea, especially considering he has just ordered a jaguar... but hey, I get paid
If I do it, that's how I'll do it (extra routing, epoxy and re paint) but I'm not sure he'll want to repaint. He says he likes the rough and damaged look so having exposed wood like this may be down his alley.
One thing i must find out is why he wants it. Is it Aesthetics? Preference? There may be another solution to his problem, so i'll chat with him.
