Heard a similar tip from an old gunsmith once.

Actually, I've had a different take on this. In my experience, oil-based poly can dry okay in cold if you just give it more time and keep air moving. @henrydixon's point about heat makes sense, but I've ruined finishes by using a space heater, even on low. It can cause the wood to dry too fast and crack. I just plan for longer dry times in winter and use a fan to help the air flow. For me, that's a safer bet than adding heat.

@cameron_hayes99, we're almost trained to brush off those warnings since pausing isn't allowed in many jobs. That culture makes it tough to heed your body's advice before things get worse.

Saw an article last month calling that "percussive maintenance", an old trick that still works wonders as @wendygrant just proved.

Scraping is normal, right? I've never actually seen it cause real damage if the paint is decent.
