Well, I got the 3M DP-8005 (correct number)  Polyethylene adhesion test completed.  

  

 Took a 1 gallon milk bottle and a 1"x 1/16" pice of  aluminum, cleaned them with MEK, didn't bother to rough them up and squeezed out  a pea size amount of adhesive.   Using top notch research methods,  I taped a couple of wooden pencils together, with a AAA battery between the  pencils in paralell., so I could push the glue plungers equally.   One  syringe plunger is very small and one is much larger, giving the proper 10:1  glue ratio.   

  

 I stuck the aluminum bar onto the gallon milk jug,  with the pea sized gob of glue and let it squish out the sides of the  mating.   You have to do all of the "stickin' together" in 3 minutes  or less.  I let'r sit all night and the next morning tried to get the 2  pieces apart.

  

 There was no way...........I finally pulled to the  point of tearing the side clear out of the milk jug, ruining a perfectly good  galon milk jug and bending a perfectly good piece of aluminum.    

  

 I should caution anyone wanting to duplicate this,  very profesional, exhaustive test, to first empty the milk jug of  milk.

  

 Needless to say, I'm convinced the the adhesive  will, without question, hold a piece of aluminum to the side of a polyethylene  milk jug, no matter how hard one pulls on the piece of aluminum.    

  

 I finally got "some" of the adhesive off of the  aluminum, with a hammer and chisel, further damaging my 6"X1"X1/16" piece of  aluminum, that I had been saving for several years, ............for something or  other.

  

 Oh Well........

  

 Anyway, 3M did a bang up job designing this DP-8005  (correct number) adhesive and I'm going to take heart in hand, drill an inch and  something or other, hole in the top of my Fox header tank and glue on the  aluminum flange, so the low level fuel sensor can be installed. 

  

 I did check with 3M regarding the compatiblity of  gasoline and DP-8005 (correct number) and they told me the was no  problem.   However, once there was ethanol added to the gas, there  would be a major explosion!   (Just kidding)

Very good report, Herb! Sorry about your milk jug and your  scrap of aluminum. Sacrifices in the name of science are always difficult, but  we do appreciate you for making them.

 Herb,

  

 Sir, since you have such an well laid out Laboratory, and have used extensive and expensive equipment for this test, I was wondering,

  

 Can you do it again with Gorilla Glue and let us know the results?
