Got a stuck fastener? Try this.

Got a rusted or stuck fastener? Spray this on and come back tomorrow. It's not 100% on the first application, but I've been very successful with it. There are lots of products out there that work just as well, but WD-40 is usually a price winner. I have rarely had to use heat following one or 2 applications of this.

Magic Spray

WD Penetrating spray is absolutely fantastic. It seps down through rust and grim to loosen whatever you're trying to loosen up. I have purchased this for years to remove bolts, screws, stuck window tracks, gears, and anything you have a problem moving. Wait 5 - 10 minutes and you'll be able to move it. If you're thinking that you may have to cut whatever you're trying to get off give this a try first. Definitely will be glad you did
