G3 CF chassis and blue threadlock issue

[zegato]

Hello,
I have an emaxx with a gorillamaxx G3 CF. I used the Amor plated hexscrews provided with the kit to mount the chassis and I used blue threadlock as stated in the instructions. All screws were at their first installation.
I need now to unmount my chassis for some upgrades and checkings and it appears that most of the screws are "locked" so strongly that I'm damaging the head of the screw if I try to unlock.
I have some good tools /screwdrivers and I tried all of them in case the tool would have been responsible. But not.
Did someone met the same issue ? and how to solve it ?
Thanks in advance for all advise / ideas
Cheers

Take a soldering iron and put it on the head of the screw for 20-30 seconds. It will heat up the threadlock and allow it to release.

ok, Thanks. I red about this way of doing and I'll try.
I'm anyway suprised that these armor plated screws are "locked" by some low strengh threadlock...
