Oil for smoke or stains, Acrylic for mold mildew, acrylic is a synthetic resin so it will not feed the organic growth, it is resistant to it.

Certainly, they should all be the same color but is there any buyer resistance to having a Bosch DW, a Samsung OTR microwave, etc?

Persistence overcomes resistance...or so I'm told.

Air takes the path of least resistance, which means the shortest ducts (closest to the air handler) will naturally get more flow than the ducts further away, as Mitch stated.

It there is any situation where the hot can get to the physical ground, and that path is the lowest resistance, it will take that path.The dangerous sitaution the ground wire and that thrid prong is intended to mitigate is when something goes wrong with the neutral connection.

Today my disabled parents woke up in their home to the kitchen fully engulfed in flames.

I'd also replace W/ moisture/mold resistant drywall, rather than just use flashing and glue.

I resisted for a long time but tell everyone know if you are going to scale out start using QB from the beginning.

I would get several cans of the low expand foam for doors and windows (brand name of 'Great Stuff' is just one of them) and spray foam complete entire window bay from top to bottom.If that stays dry thru a couple cold or wet spells drywall over this area with either drywall rated as moisture proof,,,mold resistant,,, or even use cement board tile backer(that should NOT harbor mold)...Paint to match

Your electrician will tell you you're crazy, but thicker wires have lower resistance, and Californians use a bunch of current in the form of air conditioning.
