Have any of you tried any of these car gimics? Did anyone actually get what they paid for?

I've noticed that anything that actually works eventually makes it's way to retail stores. I can remember when Slick 50 was mail order only.

 

Yea, I remember in 1988 when I was pumping gas and changing tires at the local garage, a sales rep. from Slick 50 came in and tried getting my boss to carry the stuff. My boss was a 'good old boy' that never took any chances with new stuff like that.

About 2 mos. later, every Tom **** and Harry came in asking for the stuff. My boss could of made a lot of mula.

Oh well. He could've lost a lot though if the stuff didn't work.

I have and still use Duralube. I had a 74 Camaro with a 406 that ran kinda hot. I tried every thing short of an aluminum radiator. I saw the infomercials on the stuff and figured what the hay?

It did help keep the engine cooler. A lot cooler. I was shocked.
