I've searched for years for "blind test results" that have verified that a French Polish top actually sounds better than lacquer. As a matter of fact there are premier classic makers that use brushed applied "varnish" Kinkead uses Truoil, Doolin uv cured lacquer, Greven has his own process etc. I just don't agree with the idea that not French Polishing will result in an audible detriment to a guitar classic or other. I certainly see that FB is mainstream in classic guitar marketing. Sorry I have to be the devil's advocated on this issue --- FP is nice but if properly applied so are the other coatings including the modern water bore products.

As a follow up to my last post regarding blind tests --- of course a blind test comparing a "carbon fiber violin" to a Stradivarius would be for comedic reasons only -- almost sacrilegious, but is has been done and yielded some shocking results. This is a good read and evidence to me why its difficult to separate the myths from reality when it comes to comparisons of the subjective elements regarding musical instrument excellence.

Repair as good as it is going to get.

That's an excellent repair, to my eye at least! Good job.

Thank you gentlemen.
I think probably more luck then skill.

Ken....only processed the bottom side, where the previously repair was and the nail dings.
Sanded it down as much as I dared to. Filled dings and crack with CA. Then sanded it smooth.
Padded 2# cut blonde shellac with oil (about 4 coasts). Sanded level with 320, another couple of coats of shellac.
Rubbed with pumice, then again with rottenstone. In about a week or so, I will polish and buff with car polish.

Can't tell difference between top (not touched) and bottom.
