well... the time finally came to use the panel adhesive on the form for the hood. Got everything ready... mounted the mixer tube to the glue pack and loaded it into the gun. It's two part... black and yellow... big tube (the glue) is black and little tube (hardener/activator) is yellow.

Started squeezing the gun and the black material came right out... BUT no yellow ?? hmmm. Took the tube off the gun and squoze again... yellow started moving but just slightly... tube back on... same story.. removed tube again and only pushed the yellow side... the backer in the yellow tube pushed down better than half way into the tube with no product coming out. again... hmmm. I would have assumed that there was a full tube of each product... we made a hell of a mess playing with it and finally laid it aside till I can call 3M today... maybe faulty pack of material... maybe old stuff... expensive trial at 40 bucks a pack... hopefully 3m lady can straighten it out and maybe replace bad product... more as it becomes available..

3m panel bond is black. It's supposed to mix inside the tube and it'll come out black. Are you sure it's not actually coming out of the 2 part bottle?

 

Are you using the 3M 08115 or 08116? I have to say that I have used these products for quite a few years and I have never seen that happen. The trigger on the gun is a bit hard to pull just because of the viscosity of the adhesive and the convoluted maze that it is pushed through in the mixing tip. but I have never seen a 3M automix cartridge completely bind up like you describe. The 3M rep should be able to get it sorted out for you.

 

talked to the rep this a.m. she verified the numbers on the tubes that it is olde product.

this 8115 is two separate tubes that mixes in the nozzle... could not get activator (yellow) out of it's tube at all to mix in the nozzle... she said probably the thinner had gassed off and left the activator hard... that would account for only the 1/2 tube of activator... it shrank and hardened. we tried to push it out with a dowel and couldn't push it out.

getting a refund from the auto parts guy tomorrow and headed to a fresher supplier downtown... more as it happens

You could also try amazon, Ive been buying from there for cheaper, and its fresh package.

 

 

Lord also makes these products under the Fusor brand which I have been using for years with no problems .

 

Fusor is what most of the new Fords use, and it is a safe repair procedure on some of their aluminum applications along with 3m. Same with a bunch of other companies.
