This MIK Squier E7 Bullet has a series of cracks on the back and to a lesser degree on the face. These guitars have a maple veneer in front and rear (see pic 5) over the substrate wood, and are then covered in polyester. From some reading I've done, apparently something in the process in about 1987 caused this splitting to occur somewhat frequently. The previous owner used what looks like white glue in the cracks to slow their expansion. I would like to repaint the guitar after scuff sanding the existing finish. But I want to make sure the cracks are completely repaired and covered, and don't return after the new paint. I don't want to strip the whole guitar and I don't want to replace the veneer. Any suggestions as to how to approach this and get good results? Thanks.
