UPDATE:
This project has been sitting for quite a while. I just found that the woodgrain laminate is lifting around the edges and there are 1x2" areas away from the edge that are just lifting. This laminate must have been crap, as it was old, brittle, and kinda wavy. It looked good when it went on, but has failed. I used contact cement, did it by the book, etc..
Only thing I can think to do is strip it all off. I will have to come up with an adhesive woodgrain vinyl it looks like....Hope to wrap this up this spring. It's so aggravating and I wish I'd done some things differently, mostly not used plywood and just went with crappy particle board as it's original, but won't warp like ply.
More soon I hope.
