We are all likely familiar with 3M 5200 & 4200.  I look upon those products more as a gasket/seal forming product than adhesive.  And we should all know NOTHING adheres to starboard (HDPE).

So which adhesive product works best?  I found this clip to be very informative in that regard.

I know where my $$$ will be spent in future projects requiring adhesion (except starboard  :wink: )

Wow. JB Weld looks like great stuff for the right application.

Wow!  That's impressive! Those other products can't touch JB Weld.  Guess I need to get something else for the toolbox...

I've seen this guys videos and he does some really good tests.
Reminds me back in high school when JB Weld helped me fix my broken muffler on my old VW Bug :jester: JB Weld for the win.

That Project Farm guy is great.  Plastic, wood, metal, oil, honey, ATFluid, whatever you can think of to put on, in or feed an engine and determine how spectacular the failure will be.  I do enjoy destructive testing.

    JB Weld?  Are you sure you can trust it?    https://www.youtube.com/watch?v=Om83ClL7r9M    :doh:

The surfaces need to be clean to begin with.In that test you can see the paint on the file and on the JB stuck to the steel.

Yep. The bond is only as strong as the black coating that he failed to remove from the file.

     So, it looks like JB Weld stuck to the paint, but the paint didn't stick to the file?  If that's the case then.......Warning to JB Weld users:  Make sure you have "clean" surfaces before applying.  And don't apply to painted surfaces?  Is that fair?  :arms:

Sure seems like a "Well Duh!!" moment to me.  If the surface is not clean, the bonding agent (regardless of what it is) is not likely to hold the pieces together.   

Hmmm, I want to glue these two pieces of metal...  Let's see, if I wrap each piece of metal in paper, then apply the glue, that should work...   :doh:

    Yeah right!   Here's the thing:   They advertise, it will stick to anything.  Here's my advice:   Don't trust your life to this stuff.

I've been using this...

Pretty strong stuff. I discovered it when I was studying how to stick down my spray rails.

Sticks to metals, glass, PVC, etc.

If you watched the video, Loctite came in second, and it is a one part adhesive, where JB is two part.

Yat is right...  Don't trust your life to any adhesive...  That is why we have knuts and boltz   :clap:

Croakers post shows the 2 part Loctite expoy.  Is there better adhesion with this or is the one part used in the video better??  Same??

Typical one part Loctite is a cyanoacrylate which started out being used to bond skin together on the battlefield. It's a great adhesive but not as aggressive to bonding to some substrates as a two part epoxy adhesive. The other advantage to epoxies is that they have a higher use temperatures. Cyanoacrylates will only handle up to about 200°F whereas epoxies can handle up to 300°F or more depending on the formulation. There are many, many types of each and each should be evaluated individually. My comments are just for comparing the two chemistries in general.

Epoxies can also be used with fillers (talc or fiberglass) and thus can be used to fill gaps. I don't think Cyanoacrylates work well with fillers and should be limited to use with "net" fitted parts.

JB Weld is an epoxy with filler.

I used the two part to help hold the bolts when I repaired my captains chair (original bolts pulled out of the flooring).  I have not had a problem with the anchoring system since.  So far So good.  Missed a heck of a good halibut season last year becasue of this problem.

First week-end seat base tore loose --  Repaired with stainless toggles  (I thought)

2nd week-end discovered toggles had not rotated (deployed) and seat base came loose before we cleared end of Jetty.  Finally made the holes large enough to accommodate bolt heads, plugged bottom of hole with wadded paper, inserted bolt (threads up) and filled hole with the 2 part locktite.

While I was doing both of these repairs the boats on each side returned around noon with limits of nice 'buts, first day when problem arose and second while working on repair..  3rd day we got one nice fish in the boat...  Both week-ends..    :nono:
