How do you free a rusted bolt in a tight spot?
Access is usually the harder half of the job. A wide spray pattern coats everything except the one fastener you are after. Laser Penetrating Oil uses a pinpoint spray head that puts a concentrated stream exactly where you aim it, then its climbing action works into the tightest areas to attack the rust and corrosion holding the threads. When the bolt comes loose, it leaves behind a protective film that lubricates and helps prevent the rust coming back.
What does the pinpoint spray head actually do?
It concentrates the oil instead of atomizing it. On a suspension bolt buried behind a control arm, or an exhaust stud you can barely see, that is the difference between treating the fastener and misting the whole underside of the car. Less waste, and you are not soaking a brake rotor you will have to clean afterward.
When should you use Laser instead of Thunderbolt?
Both free seized hardware, but they get there differently. Laser is the thin, concentrated one for pinpoint work in tight quarters. Thunderbolt Penetrating Oil foams on and clings, which is what you want on a vertical or overhead surface where a thin oil would run off before it did any good. Plenty of shops keep both on the shelf and pick by the angle of the job.

Frequently asked questions
Does it protect the fastener afterward?
Yes. It leaves a protective film that lubricates and helps prevent future rust and corrosion, so the bolt is workable next time instead of starting over.
Can I use it on a motor that got wet?
That is one of its jobs. Laser is effective at displacing moisture on motors and equipment.
The bolt still will not move. What now?
Spray it again and give it more time before you lean on the wrench. Forcing a seized fastener is how you end up drilling out a snapped bolt, which costs a lot more than a second application.
How do I keep it from seizing again?
Coat the threads on reassembly with Excel Heavy Duty Anti-Seize. Its copper and graphite base is made to stop galling and seizing on threaded fasteners.
