I'm sure he does a nice job.
I always kept a photo file so that if asked I could provide photo evidence with serial numbers that all parts had been stripped properly. Maybe he does the same?
You say much ado about nothing but I've seen plenty of half jobs over the years so it's always nice to see photo evidence and my comments are directed at the half job photos in that listing.
I know you've painted a few, can you post a link to some pictures of your repaints? I'm always interested in other painters work.
There was a user here who posts infrequently who repaints. I almost bought an M2 from him but was utterly disappointed. He was from canada, if you have any doubts that whoever you find might be him I'll share via PM.
