Fixing a dull spot on my guitar

Post by sfcmikej » April 9th, 2018, 8:21 pm

Hey all,

I am just getting back to playing after about 20 years away from the guitar. I pulled out my acoustic guitar, it is a Morris PA50 acoustic electric, I had autographed by Joe Diffie. Back in the day I was concerned that the autograph would be damaged by playing it but buying another one was not in the budget back then, plus it played great.

I took it back to where I bought it and they covered the autograph with what I was told was polyurethane. That was about twenty five years ago. Now I notice that the spot they covered is very dull and it definitely takes away from the aesthetics of the guitar.

I am looking for some guidance on how to fix that spot without having to refinish the entire top of the guitar or damaging the autograph. I am a little worried about damaging the rest of the existing finish and I would really like it all to blend together seamlessly.

Any ideas or guidance?

Thanks

Mike J

Hey All,

Although I didn't get a response here I found some stuff out on Youtube and I am not new to refinishing wood. I bought some Meguiar's Mirror Glaze Fine Cut Cleaner at an auto parts store. As you can see it is a 5 on a 0 (light cut) to 10 (heavy cut) abrasive. I used a regular waxing pad from the auto parts store and made it damp and rubbed on the product polishing the surface then wiped it off using a microfiber cloth. It worked great although I went a little too far and damaged the autograph a bit. Maybe I should have switch to the lighter cut compound.

I also got the finer cut polishing compound which is labeled as a 2, and some Plexiglas polishing compound that would make it like a mirror but found I didn't need them and the first compound pretty much created a finish that match the rest of the guitar and I was starting to damage the autograph


The autograph was done with a sharpie and I am considering whether to repair it or not. What is you opinion on that?

Also, I think I essentially removed the polyurethane protective cover that the shop put on. I want to protect the autograph and I am considering some of the wipe on thin polyurethane products out there. I want it to blend in with the existing finish. Any ideas on how to do that?

I added the pictures below so you can see the result and the product I used. Unfortunately I didn't take a before pic so you can't see the difference.

Thanks for your input.

Mike

No, don't try fixing the autograph. It's worth more "faded" than "bodged"

I think we can all use this as an object lesson - stuff you use to polish your car is ok with your hunk of metal in the garage, but will mess up your substantially more delicate axe

Thanks Alan, I was thinking the same about the autograph. I have to differ with you on the other comment. It worked exactly as I expected it to and as advertised and demonstrated on numerous sites. I made the mistake of not being cautious enough. Probably should have left the beer drinking to after the repair. I probably should have used the lightest cut polish first to see how it would do. I am thinking it was my impatience not the product that was the problem. It restored the luster to the finish and has been able to repair a few other scratches perfectly in the finish. I am very pleased with the result just disappointed that I went a bit too far. I offer that as guidance to others who may have issues in their finish they want to repair.

I am still looking to some how seal the autograph to prevent any more wear. Any ideas out there?

Thanks again Alan for the input, very mush appreciated.

Mike
