Caulking around furnace vent?
Caulking around my furnace vent is cracking/shrinking, however it is still playable.
It also has black spots that look like mold. No other area on my 5er has these spots, or is cracking/shrinking.
What do I use to fix or replace? Do I need to completely remove the old caulking? It appears to be being different than the caulking anywhere else on my 5er.
