Ah, the magic spray. The one that loosens bolts, stop squeaks, and bolts the door against corrosion. Every sailor has their favorite brand miracle spray (WD-40, CRC, LPS, CorrosionX, etc.), and that brand will often live up to their expectations. However, as we've found in our testing, some sprays are clearly more magical than others, and many of the biases among sailors aren't fully justified.
And then of course, there is a lot of confusion of which spray is best for what job.
Yes, there are some spray products that claim to be everything under the sun. But given the wide range of expectations we have, it is physically impossible for one spray to fit all our needs. Some spray petroleum products are good for loosening bolts, some seal electrical connections, some protect against corrosion, some even claim to improve conductivity.
Over the years we’ve put these products through a variety of tests, with some surprising results. In one study, we found an anti-corrosion coating that actually seemed to promote corrosion. Here's our greatest hits, so to speak, of miracle spray coverage.
To test products that claim to protect electrical connections, we immersed store-bought electrical toys into a fish tank (PS September 2007.)
CRC Heavy Duty Corrosion Inhibitor came out a winner in our test of anti-corrosion spray coatings (PS April 2007) .
Some products that claimed to improve electrical connections and fight corrosion fell flat in our test (PS April 2017).
Seized bolts on an old trailer bore the brunt of our anti-corrosion spray test (PS April 2009).
The bond-breaker’s tool kit: vice grip, impact driver, cold chisel, lump hammer, and nut cracker (PS April 2009).
