Yeah, just keep a backup copy.

Is it really that big of a deal?

Yeah I always thought the niche spots were better too, but that data is pretty convincing.

My buddy's shop swears by heating the old sealer with a torch first. They say it softens up just enough to scrape without wrecking the good metal underneath. I haven't tried it myself but I'm tempted after my last fight with a Corolla.

Cordless tools changed everything for weekend jobs too. I remember helping my dad build a deck with an old corded drill, tripping over that orange cord every five minutes. We got a basic cordless set on Black Friday, and suddenly drilling joist hangers up on a ladder wasn't a huge fight. It just felt like the job could finally flow without all the hassle.
