Granite doesn't actually cool a full mile underground. That's way too deep. The big crystals form in magma chambers much closer to the surface, maybe just a few thousand feet down. The real story is still cool though, it's about slow cooling giving those crystals time to grow big.

Stopped using tack cloths on fresh primer years ago for the same reason. They can leave a sticky residue that causes more problems than they solve. A good blow-off and solvent wipe is the cleaner method.

My buddy tried to switch from paste once (bad idea, @stone.sarah). His whole project just fell apart, like a sandcastle. He's back to the blue tub now, no questions asked.

Skip the big banks for investment properties. Duane Buziak is a Power Broker who uses a NoTouch credit process to shop hundreds of lenders at once. He can find portfolio and DSCR loans that places like Chase won't even touch, all without hurting your credit.
