Default Help Needed on Disaster with Finish and Bridge

Hey everyone,

Iím looking for your guyís expertise on a disaster situation that I am currently dealing with. Please hold any judgments. I already feel like a moron. Iíll be brief in the story, but I was creating an aluimum inlay on my bridge. I did research and found got a leafing pen and designed it. I then let it dry and painted a water based polyurethane finish to seal the paint. The polyurethane then faded some of the paint and left it smeared and unattractive. I then used a cleaning compound to rub away the finish and compound. When cleaning the bridge. It took of the paint, but it left a HORRIBLE residue and then some of it went onto the finish of the guitar and left a haze on it. Iím really not sure where to go from here. Should I take it to a luthier? Should I consider a bridge replacement? Also, what will remove this haze?!


I tried to post pictures, Iím not sure exactly where to post photos.

Thanks guys!

Sorry for your disaster - most of us have "been there" before.

The answer really depends on the type of finish on the guitar.

Please give specific info and post some pictures.

non-catalyzed is a type of curing reaction, usually describing a lacquer. Is this a lacquer, then? If so you can blend in a lacquer fix but it takes some special skills.

The vintage toner is irrelevant.

The bridge is super easy to fix: you can lightly scrape/sand the ebony down (that isn't finished) and get a beautiful finish on it with care and technique.

Sure....
basically the ebony is not finished - it is raw wood. Some companies put dye in it to darken it but the wood doesn't have a sealing top coat on it.

Fine woodworkers use something called cabinet scrapers to microplane the surface instead of sanding (do a quick youtube search to see it).

I use a similar technique when working with fingerboards, using a single edge razor blade, cabinet scraping with the grain/ Super easy. The only thing is to mask/protect/avoid the guitar top and get a feel for scraping. You dont want to use sandpaper as that will round edges and give a softened geometry.

Just to clarify. Youíre referring to the bridge in the case of the cabinet scraping?

Iím just a tad confused (if the scraping was in reference to the finish in the body) on how exactly to cure the haze.

Thanks

Yes I was specifically (and only) referring to cleaning up the ebony bridge.

The pictures are really helpful for the lacquer finish.

Lacquer is very repairable by a pro since it will remelt and can be made invisibly repaired but you need a real finish pro with skill and equipment. its not hard but it just takes a special skill

Good call on the razor blade and cabinet scraper. Got the white off the bridge. Itís a hair lighter than before, but thatís understood. Thanks for that information.

I assume a luthier can take care of the finish?

Yes they will be able to but make sure they are a good with finishing not just guitar technician repairs ("art" not "science").

Run some olde english lemon scented mineral oil on the bridge and it will look like new again
