filled with Sanding Sealer as in Zinsser's 100% wax free Universial Sanding Sealer? not tat that matters much just want to be sure that is what you ment. Well tha tis a pretty big sand through. ods are there will be a some what noticable color variance when your through. I suspect that recolor with shellac and refinish the area is best you can do. Now there is some disagreement with what I am about to say here but I would never put any epoxy over shellac. my experiance has shown repeaded adhesion issues. On the other hand Shellac adheeres well over Zpoxy or any other epoxy. |

yep i would have to agree Laurent. the odds of not seeing a color varient in the finish repair are slim. |

Thanks for the input, guys ... Filippo One other thought, you could strip and re-do just the heel area a little darker to make it look like a violin neck. You might have to re-color the head stock darker to make it look right though. Never tried it, just a thought though. |

I was never successful at matching the colour on a sand through, even on a non stained neck… Maybe others have had more luck. Interesting heel cap shape BTW. |

I've had some luck with epoxy darkening an area where I've sanded through. Did you use the same grit sandpaper in your effort to refinish? The heel is the worst area to match, but if you use the same sandpaper you used prior to finishing you might end up with something less noticeable. The area you are working on may have become smoother than the surrounding area from the extra sanding. Epoxy has a lot of wetting ability and might do the trick. . . but I'd probably cut my losses and refinish the whole thing. |

I have restored many an antique and color matched, but it takes a lot of effort and is usually something that isn't that uniform in color. I'd say strip it. But one thing first: From the photo it looks like the shellac might have hazed and thus whitened. Is that not possibly the case? I don't know all the materials that were used, but I've had shellac haze like that and kill the color under it. Just a thought. Not that it makes the repair any easier but... |
