hello, I think I join the conversation a bit late .. but yes , once I saw the shadow under the sticker .. you can read some text in the external border. Clear indication of sunburn on paper with different colors
I don't think there is any solution, as the external layer of paint is burnt. You can't burn just the little circle without covering the whole guitar and leave the sticker area in the sun.
If anything , you have a very exclusive model 😆 sunburn Explorer Lee Malia. Exclusive paint job by the sun over the years.
I am surprised how good the rest of the instrument is , considering the slow cooking.
Just play your guitar and have fun with it.
