Review on Permatex 84109 PermaPoxy Minute Multi Metal by Chris Scalia

Used for two pieces of 304 stainless steel, 20 gauge. Both cleaned with alcohol. "Grubbed" their flip disk. I mixed the binders and applied to one piece and then bonded with a C clip for 24 hours. After 24 hours I untied them and then tried to separate them. Either I have some sort of high-performance capability to rip connected stainless steel pieces apart at 4500psi or this stuff isn't working as advertised. To be honest I would just like to know what I could have done wrong than to give this epoxy a negative review. Should the stainless steel parts have been better "cleaned"? Using a petal disc may have just polished the metal. Maybe I should use a hard drive instead of a flip drive for this prep? In any case, this is not possible out of the box and according to the recommended preparation of the material.
