Yeah @phoenixa64, my buddy's did that on a tight corner.

Hold on, I've got to disagree completely. A garden sprayer sounds like a messy disaster waiting to happen. You get way less control over the adhesive amount, and the overspray gets on everything, your floor, your tools, yourself. I tried something similar once and spent more time cleaning up the mist than actually laying the floor. A good trowel gives you the perfect, consistent pressure you need for a solid bond. That sprayer trick is just asking for a seam failure down the road when that thin coat lets go.

Wow, $450 for a polish job is brutal. That oily stain etching into new granite is a nightmare. I've heard of plumber's putty damaging stone, but actually seeing it sweat oil and ruin a sealant is next level. Makes you wonder why they even sell that stuff for kitchen sinks.

Honestly, it's like when I finally got a good kitchen knife after using a cheap one forever. You don't realize how much extra work you're doing, or how much you're fighting the tool, until you try the right one. It's not about gear for gear's sake, it's about how the right tool just gets out of the way and lets you do the thing.

Wait, didn't they leave mirrors, not rocks? I thought the reflectors were for laser experiments. That's what makes it such good proof.
