Seam Sealer/Caulk Instead of Duct Tape

[RoundTwo]

While pulling out the insulation, I noticed how poorly adhered the duct tape was in so many of the places around the cabin. Under the tape, there’s also a lot of non-hardening caulk, a product I grew up knowing as “dum dum”. Since so much of the tape wasn’t adhered well, I started thinking about using something else when things go back together.

Seam sealer isn’t new, and was certainly available in 1988, when my plane was built, so I have to assume there is a very good reason tape was used instead of a more permanent solution. I’m guessing the temporary nature of the duct tape is the driving force behind its selection for air sealing the cabin.

Is there anything I’m missing? Would it be okay to use a tube based sealer instead of tape?

Thanks,

A friend who is retired from the airlines as a mechanic, gave me a roll of Boeing duct tape. This stuff is amazing! It has “Boeing FAA approved” printed on it. I have no idea where to get it, or what it costs. I think you could put a single piece across the roof of your car and pick up the car.

Be careful using things from other sources, some of it could be corrosive or combined with things that are there could in combination be bad.

I’m not speaking to the post above but going to the hardware store and just picking some kind of adhesive or whatever.

All fabric duct tape I’m familiar with over time from I think temp swings etc the adhesive hardens into something that’s difficult to remove, the actual metal foil duct tape seems to be superior from what I’ve seen
