The adhesives and sealants we use and trust.

[rossvtaylor]

Hi all,

I was asked about adhesives and, so, I made another video. I hope these suggestions are of help to someone. And, please, let me know if you are aware of better options in any of the categories...or what your experiences with these products have been. I'm always looking to learn new stuff.

Be well and...let's stick together.

Okay, that was corny as hell. But I meant the "be well" part...and happy travels.

3M 5200 really should **only** be used for jobs you never ever want to undo, much more an adhesive than a sealant.

Separating the parts often means destroying one side or the other, or both.

4200 is also an adhesive, as opposed to e.g. butyl rubber tape

but much more rational for things like ports / hatches, fans, aircon units any hull penetrations that may need re-bedding replacing one day.

I absolutely agree...and that's a big part of what I like about it. I consider it to be structural. When we add new skin during a roof raise, we run a bead of 5200 down the vertical ribs and press the skin into it. And when we install solar panels, I scuff sand down to bare metal and use 5200 in addition to the mechanical fasteners...as added security. A 3x5 inch "foot" on a solar panel bracket should offer (at least) 2000 pounds of anchoring force, in addition to the mechanical fasteners. It's good stuff.

Thanks for the tip on the 4200. I'll get some and try it out. How would you compare it to the Dynatron or Sikaflex products I'm using?
