Best double sided tape to hold LED under elevated layout track

When I do passenger car LED upgradess, I put a spot of CA adhesive or hot glue in a few spots to "help" the tape.  Spots of RTV would work as well.

What you need is 3M trim tape.  Do a search for it.  Strong stuff.  Typically it adheres fender flares.

John, Volphin, thanks for the suggestions...

If looks is not of great concern,  I hold objects under my elevated sections with Velcro which allows removal for modifications and maintenance.   I have some "once and done" LED strip lighting which I installed with contact cement to avoid future sagging.

3M VHB tape ... 3/8" is perfect for LED strips...

It's a personal foible of mine, I admit, but I don't have much faith in the ability of tape to stay attached over the long term. I prefer using CA glue and mechanical means of holding the tape, such as small strips of plastic glued or screwed down crosswise across the tape.

Fully support the recommendation for 3m trim tape.  Designed for automotive trim, best I've ever found.

It's going to be a bit of work and effort but double sided carpet tape should do ya right. That stuff in uncommonly sticky!!

Velcro strips Ed, work great for this type of application'..... Easy install as well..... Or you could cut some thin strips of balsa or Bass, 1/8"  and glue across the space between the led on the strips.  Space the strips 6, 7 inches apart.  I think your elevation track is plastic, no.  If it is, any decent white glue will work, or CA.  Remember though. CA is difficult to undo if you want changes down the line...

If the surface you are trying to adhere to is made of wood and has not been painted, I have not found any tape, including super aggressive velcro or automotive trim tape, the will hold up!  Bare wood still has a degree of sap and eventually it will cause the adhesive to fail.  I would suggest that you paint the surface first or use a mechanical fastener.

Good luck,

Don

I used contact cemet.  Weldwood brand I think.  It's tan/brown and comes in a small paint can.

I removed the backing for the sticky side of the led strip about 12 -24 inches at a time.  I used a toothpick to dip into the cement to swab the sticky surface of the led strip.  Then I put the strip in place and used pieces of blue painters masking tape to hold the led strip in place for the cemet to cure.   At the end of the coated section i used extra pieces of blue tape across the led strip to hold it in place while i peeled the backing off the next section of led strip and swabbed more cement on the next section.  A couple of days later I removed the blue masking tape and it has held up perfectly for three years.

Recently I removed and repositioned a section.  No problem to gently smoothly pull it loose and put new cement on and tape it in new orientation.

Gents, thanks for the great solutions. 

Ted, the FasTrack is on 1" pink foam board and that sits on 3/8" plywood.

I think contact cement will work best on the plywood.... As mentioned, by other posters, nothing  else will hold the strips to the wood as the CC..........

The best I have used is Duck double sided tape.  It's also thin.

It's so sticky, the most difficult part is peeling off the backing film.

John, I had trouble taking off the backing strip...it would drive me crazy.  Then I found this on YouTube... Works.

Doesn't work on the Duck tape.  Just tried it.  The sticky side of the tape doesn't stick to the blue side of the backing film.  

But if you can manage to peel it off I know of no other double sided tape that sticks as well and is also thin.  Folding over the end to leave a section of film always loose works pretty well sometimes.
