Sealing propane locker openings

[batkins61]

I recently had to pull my entire propane locker to get access to the back so I could remove the faulty solenoid. It was attached to the regulator which was screwed in from the outside of the locker with 4 sheet metal screws.

Someone had used what looked like silicone caulk to goob all the screw heads and also used it around the fitting that seals round the propane hose to the stove. I removed the fitting and discovered that they had also used some other sealant inside the gasket in the fitting, rendering it pretty much useless. I have a new fitting and am ready to reassemble. My question is, what should I use to seal the little sheet metal screws that go through the locker wall and into the mount holes in the regulator, and around the appliance hose fitting where it screws to the locker wall? I'm assuming the rubber gasket that seals around the hose doesn't need anything, correct?

Thanks!

I would think silicone would be fine.
