Amazing
Loosened my stuck wing mirror and seized compressor drain valve both within 10 minutes after hours of no luck with straight WD. One of the best purchases ever.

Worked great!
Couldn't get a rusty driveshaft out of a washer, to replace the bearings. Hours of hammering didn't budge it. Put the WD40 Penetrant around the rust portions of the drive shaft. It took a few applications and letting it sit over night, but the drive shaft came out with one hit of the mallet, the next morning.
