I have a bottle of spray paint that matches the color under the pickguard exactly, so I think I'll use that, will that stick?So if you're going to repaint in LPB.. I'd leave the green on, scuff it so new paint will stick and reshoot it with the new color. Thats a heck of a lot easier than stripping it down, imho
Yeah I was going to test it under the pickguardAlways test in a small area that will not affect the visible parts of the guitar. Many have paint in the neck pocket or body routs that you can try the new paint on.. and if it gums up, clean it up with a little solvent and nothing is really hurt in the process.
But always, always test before committing to the paint. Life gets very sad, very quickly if you don't.
"poly" is used for a wide variety of finish types. I think the older polyurethane finishes would yellow over time due to UV exposure, but the newer UV-catalyzed polyester finishes (relatively new carryovers from the auto industry) resist yellowing a lot longer.The clear coat yellows over time due to exposure to ultraviolet light. Sunlight is the biggest culprit, but all lighting has some UV. Even poly is not immune to this.
