I am making a base to go inside something and need to adhere the LED strip to the plastic. It doesn’t like to stay put after a while of use and unsticks, curling up and showing up poorly. What can I use to wipe the plastic with so that the tale sticks and stays stuck? The LED uses 3M tape, so not junk tape either.
Tape the LED strip down, and then run a bead of thin Cyanoacrylate adhesive all the way around both edges of the strip. As long as there’s no mechanical stress being applied to the strip, it should stay stuck for at least however long it takes the print’s plastic to degrade.

I’ll give it a try. Thanks
If possible you might look at Cyanoacrylate activator (like 2P-10) Put activator on one surface and glue on the other and press together.
You might also look at something like UV actvated glue.

Edit and test anything on scrap before use on a production piece, but I bet you knew that.
Have you tried using hot glue?
Yep, its what I tried for securing wires internally, came right off. I found an alternate method, I made a 2mm plate, secured the tape to that, then glued that in place with thin CA. It put the LED right into the opening for a brighter light source.
Here’s the finished product

Nice, simple and eloquent solution.
+1 for UV resin as a glue if your situation allows
I find CA to get very capillary along layer lines and looks like junk white frost in a large radius from where I apply it
JB Weld ClearWeld works very well, but is very permanent.
Permanent is what I want. I’ll give the JB weld a try.
I hope it works well for you too. Clearweld says it’s 5min kick/1hr cure but if you’re clamping together what you’re gluing, I recommend 4hrs. Maybe it’s my cold workshop, or maybe it’s the nonporous plastic. But your patience will be rewarded
