After the decals came off I gave the cabinet a sand inside and out, as the decals had been laid on bare wood and their removal had made the surface a bit rough.
I then moved on the task of repairing all the cracks, divots, and failed joints where the glue had let go. I found the best way to glue many of the joints was with a syringe and needle filled with high strength (outdoor rated) PVC. Most of the time I found I only needed about 3-4 ml of glue to get the job done as I was able to be very precise with the application of the glue.
