I am with Faster, absent known issues I wouldn't be in a hurry to rip it apart. If you do have an issue then you obviously have to deal with it.
To fill a horizontle hole just tape up one side, and put a strip of tape covering all but the very top on the other. Using a syringe fill the hole completely. The small hole should keep the thickened epoxy from pouring out. Then add more tape to cover the small hole. I like painters blue tape for this stuff since it removes well, but cellophane tape is also nice since you can see how full the hole is as you go.
