Location: NW Washington State | Would a super glue- or any glue- that's formulated to adhere to plastic be needed so that it would stick to the bowl? Most superglues and epoxies aren't very good for plastic. To stick two pieces of plastic together you have to look carefully to find one like "Plastic Welder" or "Plastic Surgery".
I don't know if this is what's needed, just asking.

| Isn't there some kind of wood kerfing adhered to the bowl that the the top is then glued to? I don't think the top is glued directly to the (really) thin bowl directly... |

Location: SoCal | It's a plastic or fiberglass ring that's attached to the bowl. It has a lip. The top is mounted to that. Take a look inside your guitar. You'll see it..... |

Location: New Hampsha | Elmer's wood glue works great and flows into the crack just fine.
If you know anyone who is a physical therapist, hit them up for one of the giant rubber bands made of sheet rubber that's about 8 inches across - it makes a great wrap-around clamp on the roundback/top joint. |

Location: Michigan | From my experience epoxy will adhere to both fiberglass and wood. May not as well to plastic. Nothing really adheres to plastic that will adhere to wood. The bowl is fiberglass so as long as you scrape or sand away any paint on the inside where you have to glue it should adhere. If you go to Home Depot they have various types of epoxy. Get a slower setting epoxy that will give you more work time and will last longer under extreem conditions.
Superglue does work somewhat with plastic but not really well. The trick is to have a glue that will either be able to impregnate into the material (wood) or become part of its composition (fiber glass). Epoxy fits both those bills.
There is a glue that will actually sort of melt plastic materials and allow them bond together but it is not readily available and will not work with wood. I cannot remember what it is called but we have used it to fuse pieces of acetate together.
A slow set epoxy has the added advantage of being a pretty good filler. Just make sure you get all the excess off before it sets. Wipe it with a rag and then dampen another rage slightly with methanol and wipe it clean. Not so much methanol as to get into the glue but just enough to clean any spill over marks. |

Location: NW Washington State | From my experience, ordinary epoxy and superglue work poorly for plastic. The glues that melt plastics are made for specific varieties of plastic.
There are "super" glues that are made for plastic. Here's one: http://www.itwconsumer.com/catalog.aspx?prodID=227
There are also epoxies that are made for plastic. Here's one: http://www.devcon.com/products/products.cfm?familyid=182
These were easy for me to look up since they're the ones I have handy and have used before. I'm sure there are other brands.
I'm not claiming that these are the best for guitar or fiberglass repair, but if I were going to try an epoxy or superglue, I'd use something like this instead of a general purpose product.
Does Elmer's or other wood glue stick to fiberglass?
