I can't believe you haven't mentioned "sugru" on the show - it's a moldable glue that turns into rubber and is very easy to remove. It has the consistency of Play-Doh for about 30 minutes, then hardens like an epoxy into a strong rubber. I forgot to buy a mount for my flight controller, so I created one using sugru. Look at the red rubber on each corner of the flight controller. I have no affiliation with the company, but I recommend you look at some of their examples on their website: sugru.com.

Not quite as good as the pro version but you can make a similar substance from corn starch and silicone caulk.

I had Surgu, liked it but it has a short shelf life. (even in an unopened package)

The silicone and cornstarch is a great alternative, and can be made when needed.

Brett Childress What's the ratio of cornstarch to caulk?

[G+_Eddie Foy]

Its actually kinda wide open.
