My guitar’s pickboard is fairly messed up (cracked here an there and contains a spot or two where the plastic doesn’t meet), but provided I treat it gingerly will probably not crack any more. I don’t care, but like what’s still there. I would like to keep the fretboard from suffering more however. I’ve never had much success with glues that work well on plastic but I’ve been told that SuperGlue should cement the cracks and (using the thicker version) fill up small gaps and valleys. Q1) Is this true? Q2) I gather Stewart MacDonald is the end-all when it comes to materials to use on guitars, but…is there a big difference between their super glues and the many other brands (e.g., Loctite super glues and gels)) available at Home Depot for a fraction of the price? Q3) And what’s the difference between (a thicker?) SuperGlue and a SuperGlue Gel?
