Vandelism proofing my trunk...need help...

A few days ago, some a$$grape tried to break in the trunk of my lumina. :swear:
Like most of our cars, it's easy to pop the truck lock cylinder out, cause the metal plate holding it is thin, so quite some time ago, I replaced the lock cylinder with a HUGE Carriage bolt and a thick lock washer and nut on the inside, which prevented the punk from actually getting into my trunk. But the screwdriver marks are still there and there is some sheet metal damage. I'd like to find the punk and :nutkick:

And there's nothing really in my trunk besides a few tools in case of emergency. no amps, no subs. (haven't installed them yet, been lazy)

I bought a 16ga steel plate to weld inside the trunk behind the lock cylinder hole to prevent someone from punching through, and I'm going to fill the lock hole with Magnum Steel, and do the fiberglass/bondo/repaint thing. Do you think 16ga is strong enough to withstand another attack?

another way would be shaving the lock cylinder and using an electric solenoid only to have it open by remote which would solve that problem quick

I reread my first post and it wasn't clear... shaving it is exactly what I plan. I already have a electronic solenoid installed.

A common way Police protect their trunks is to put a chain through the trunk lid to the body inside the trunk. Then you can just put a metal cover over the trunk lock. Obviously you would have to have an electric trunk release for access to the trunk.
