Strange! I own a much cheaper version of a Goldtop, a Studio 50's Tribute. I have it since the end of last year and kept it in that really cheap gigbag until a week ago when I finally bought a hardcase. I live in an old house which is under continous (lifelong) reconstruction, with drastical environmental changes happening all the time: I do paint the walls on weekends, so there's extreme humidity conditions inside. Now it's very hot here - nearly 40 celsius degrees in shade...and I have no issues on my guitar, neither with the finish nor with other parts. It was checked by a luthier 2 weeks ago (what I regularly do) and it has no issues at all.
