Hi

I've got a guitar that has a small piece of paint chipped off the size of a nail. The previous owner has just glued the piece back on and it's not looking good. I think the guitar has poly finish. Is there any change this could be fixed easily just by filling the gaps with glue, sanding it even and polishing or is the end result going to be horrific? Any other suggestions? Can poly finish be fixed in a small area or does the whole top need a respray?

Using CA glue to reattach a chipped off piece of poly seems to be pretty standard. Having said that on a dark guitar it probably would never be an invisible fix. I think you'd always still see the chip. I've masked the spot off and used progressive grits of micro mesh sanding sheets to smooth the CA fix, but again it was never invisible.

Try this. I have used it with great success on poly.

The way that looks like it was done, you will always see the edges of the chip.

I probably managed to make thing worse. I sanded the chip even with the top with 600 grit wet paper. Then I used marker on the spots where there was no paint and applied CA on the gap. At this stage everything seemed ok, but after the glue had hardened I once again sanded the top to even, but somehow some paint has gone off althoug the top is dead flat and there`s CA over the parts where the wood can be seen. How is this even possible?

Any suggestions how to go from here? Or is my only option a new respray and finnish?

I'd have a go at it with the black Fill n Finish. Be aware that it's translucent so may not entirely mask the wood. If your finish is completely opaque, you'll have to use some black pigment from their Mix n Match Black and White set along with the Fill n Finish. Check their videos and good luck.

Welcome to the world of finish repair...

First, throw the markers away. Magic marker was your first mistake.

The bare wood is from the fact that whomever glued the chip back in did not get it back in all the way and tight. This was the cause of the original white line. Since the chip was most likely glued in with Ca when you sanded through the chip you wound up with clear finish on bare wood. This will require sanding back to bare wood now to attempt any decent looking repair....

Or you can accept that guitars get chipped and dinged. You can't keep them looking like new unless you leave them permanently in the case and never use them. Sometimes we get hung up on cosmetic issues. I am getting pretty old too - and it shows!
