In the back corner of our Casita
where we sleep, there are 3 small metal brackets (for a small TV wood shelf for I guess). Each bracket is secured through the exterior wall with two pop rivets. We've never needed to use the brackets. However, they're a problem since the brackets just above my wife's head during sleep times. Consequently, they're semi-dangerous. I want to eliminate them.
If I drill out the rivets, how do I seal the holes? Is there a cosmetic application on the exterior surface or just live with the visual of 6 previous holes? Thank you for any response(s).
