Just testing to see if makes a difference in the consistency performance through out the flight. Vibration test I guess, I may be too cautious but the planes I have are over 15, 17 and 20 years old with old tin uniflow type tanks. They don't leak. I just think over time they may have freed up a bit ? I'm not gonna lie, today, one fell off after being pre flight checked. The other was slid forward ( ? ) after each flight.

I have used plastic electrical tie wraps for many years. Field repairs included. Main use is for holding tanks on profiles. As long as you have something soft between the tank and fuselage, then the ties themselves, don't seem to transmit much vibration. Mind you profiles are a can of worms for vibrating fuel tanks. I have used them on Peacemakers and Flite Streak type models, with no problems.
Makes me wonder why people persevere with profiles. They usually finish up more expensive, weighty and far less rigid than a simple full fuselage model. There isn't much in the way of time saving either! But each to their own.

I've always used silicone, like Dow bathtub sealer to secure fuel tanks. It's perfectly fuel proof and has a bit of resiliency. Metal tanks can be glued to magnesium speed pans, plywood stunters, inside scale bodies, and anything else.
In the beginning I just used Dow bathtub or GE refrigerator sealer. Now it's available in a variety of off-brands in any hardware aisle and it all works the same.
Also one more good reason to avoid diesels, as if the stink isn't enough.

Its not proof against diesel fuel, in fact if anyone wants to remove silicon glue then just use kerosene and watch it turn to jelly before your eyes.
