When I first saw this product I immediately thought about the stem lube scam on The Simpsons, but if you think about it, this product might not sound so silly. Have you ever broken a bulb because it was stuck in the socket? Next time you replace it, you could try a product like Bulb EZ to keep the bulb from sticking.
Copperwolf claims that Bulb EZ is non-toxic, non-corrosive, odorless, not silicone based (won’t dry out), and made in the USA. One ounce of Bulb EZ will run you about $4.
