thanks a lot for your suggestion and input...it was very helpful...it
has given me great ideas...yes this is cheap cabinetry, current mobile
home quality. As 'R' pointed out there probably was water damage, but
it is now dried out and I think your suggestions will work.
Thanks again for your insight!

is to chop a piece of quarter-round or shoe mould into suitable lengths.
