This is what it looked like before I took it apart:

Before it goes back in, it will need some remedial action to fix some areas of water damage, and some of general wear and tear.
A lot of the melamine edging strip has come off, and whilst I know that new edging can be glued on, I am wondering if there is anything else that can be done to refresh or update the melamine?
Has anyone had any luck with painting melamine doors? if so, what sort of prep and primer would be good?
In some cases the wood is worn or chipped, so I will need to replace the section with new wood. Getting sheets of matching melamine is unlikely, hence my thinking about doing something else.
Are there other chipboard or plywood products in sheet form that are already laminated with a plastic or melamine coating?
Advice, ideas, pictures or what works or doesn't all very much appreciated.
Thanks
Mark
