On CAPS, 91.5% of the 153 members who have rated WD-40 believe the stock will outperform the S&P 500 going forward. These bulls include dcrednek and baekeland108.

Just last week, dcrednek tapped the stock as a particularly slick selection: "WD-40, the timeless stalwart of aerosol lubricants (and far and away the king of market share among this group of products). ... Who says buy and hold is dead?"

WD-40 might be as close to a one-hit product wonder as you'll find, but that single product has fueled consistently healthy performance over the years. WD-40's returns on equity are consistently in the 20% range, and have never slipped under 15% in the past decade. And with a lower debt-to-equity ratio (0.05) than rivals Church & Dwight (0.3) and Clorox (25.6), as well as other cleaning specialists like Procter & Gamble (NYSE: PG) (0.4), Colgate-Palmolive (NYSE: CL) (1.35), and Unilever (NYSE: UL) (0.66), WD-40 seems like a relatively safe pick, as well.

CAPS member baekeland108 sums up the bull case:

I try to avoid companies offering a mono product (at least mix it up, slap a new label on it with the wording "New & Improved" and viola a new product). WD-40 does not play that game: They know what they have; the product works famously for what it is listed as and then some. ... WD-40 is a product that has been used by too many Grandfathers to count.
