poly finish repair

[G-bo]

Hi folks,

I have a guitar with a good size crack in the finish.It's a little hard to describe but the finish has actually curled up and
you can feel the ridge very easily where it is "cracked".The finish is a quilted sunburst with a clear poly on top.I'm not
expecting to do a flawless repair but I would like to do the best I can with it.It was like this when I received it so I could
not say what happened to it.Looks like maybe something was spilled on it or perhaps exposed to heat.Hoping the
photo will make it a little easier to see.Would appreciate any info you could tell me.I have seen a lot of articles where
the poly finish was filled with crazy glue and sanded down but I need to find a way to make the poly finish lay flat again
so this situation is a little unique I guess (it looks like if you saw a map and there was a mountain range,best I can
describe it,I would say the ridge is about 3 mm high).
