That was unintentionally (I think) amusing and sad - much more reflective of the typical improvement project gone south than your typical rehearsed-and-scripted "This Old House"-style bit, completely missing the mark in the expected outcome. I couldn't help but think of Dan Aykroyd as Julia Child...

Huh? "How To Form Small Concrete Projects The Easy Way"? This is 95% about consolidation/vibration, maybe 5% about *forming*, and more specifically about using blue tape as a release, which isn't a bad idea, but...bait and switch, IMHO.

For oil-based paint, what could be easier than immersing brush or roller in a bucket of water? Oil and water don't mix, and water keeps the solvents from evaporating, so the paint virtually never dries. Using oil primer, I've done this for up to several weeks without a problem. After removing from the water, a light shake of the brush flings off any water droplets. As for the roller, on removing from the water, you might or might not want to roll out the remaining wet paint on a scrap surface, depending on the project.

For water-based stuff, I usually will put a brush in any handy plastic bag and freeze it for use the next day or so, but I have found some paints get 'gritty' from freezing, so I don't think I would use this method for other than a primer.

Appealing idea and looks good [new], but yes, lacking in detail and clues about the aging process.

I'd be absolutely sure to ground this countertop, for one thing, and not rely on the sink to do so (even if the sink is indeed metal).

I'd also want to know what happens when someone naively breaks up a bag of ice, frozen chicken-wings, etc on the surface...wouldn't it end up pebble-finished and/or distorted, as the metal stretches?

The photo of the 'turned down' seam doesn't appear to represent the described 'sitting seam' (hooked into the kerf, the description seemed to be) as shown in the adjacent drawing - photo looks instead like a lap-seam, from the lump. I like the kerfed seam idea - and if I were to build this, I would solder that and any other joints [without a flame]...along with a hidden ground wire...
