hello,
wonder if someone knows what the material is called that seals a modern A/C-Heat Pump service access panel (to get to the coil and drip pan)
it's a black, soft, sticky, rubber-like material and there is a thin strip of it all along the edges of the inside of the service access panel.
reason I ask is that when I open the panel to clean the coil, the material is hard to keep from breaking despite a very careful handling of the panel and I would like to cleanly replace all of it each time I open the access panel.
can it be bought in bulk from somewhere online or the local HD or Lowes?
