Oh yeah...I was feeling it yesterday, too. Washing and wiping all the black rubber and plastics with the UV protect stuff. The stiffness is such a pain, but I just push through b/c there's nothing better for it than to just keep moving.
I finally caulked the kitchen sink. A thick layer of that silicone, '10 year mold free' stuff, by GE. It's not the prettiest of jobs, but hopefully it'll save/protect the particle board countertop, from the crappy lifting Thermofoil for at least a few seasons. I did prep the area with painters tape, in order to not make a total mess of it.
