Ever have a "Homer" screw moment?....

DOH!
My trailer sees to be going thru 'puberty' today. I had a "Homer" moment and put a screw thru the wall and almost put two more thru the wall. It looks like a pimple starting, then progressing to being poppable and then the explosion!
Now for my question...... Seeing as I am not familiar with repairing such holes (almost holes), what would be the best course of action to repair? I thought about just drilling the top two and putting a screw in from outside with sealant but the third hole (explosion) the metal is sticking out a bit and doesn't look like a screw could get a good seal on that hole. How do I smooth that metal down without making a mess of the .040 siding?
The REASON this occurred was that I was trying to do some "in case I decide to add access door" backing inside the wall while installing the wall insulation. I had been putting a second layer of insulation on the wall perpendicular to the wall framing and adding firring stril on the wall to add the wall panels to. After 100+ screws being installed the same way, my "Homer" kicked in and was adding the firring strip without the 1/2" insulation. Since the firring strip would overlap the studs, i had custom cut them to just fit over one side of stud and be flush on other. But in not thinking, drilled the holes and put the screws in ALL the way and what happened???
Trailer now has a case of acne, ha!
I am trying to keep the trailer as stealth as possible and thinking the access door would take some of that away from the stealth. The intent of the access door potentially would be for inside propane storage as my tongue is not long enough to accomodate because of v-nose (Neo NAMR trailer). May end up having to put one in just to fix this "Homer" moment.
Thanks,
