Holes in leading edge where stall warning vane goes

So I am not installing the stall warning vane as i am putting in an AOA system. So my question is what to do with the holes in the leading edge skin. The two on top and on bottom i can simply dimple and put a rivet in but the two on the radius would have issues. I bent a piece of scrap and dimpled it in the radius to test it and it distorts the skin. Any suggestions? I don't really want to leave them open3526.jpg
 
Use an oops rivet with a flush head small enough so you can countersink the skin rather than dimple.
 
had the same issue, after you attach the wing skin, back that area up with small pieces of fiberglass cloth and fill the holes.
 
Prep the inside area with some Schot

This, but I put a dab of micro in each hole before putting the single bid of glass on the inside. After set sand whatever small amount of micro came out the hole flush.

Bondo would be easy. Common in the auto industry, it will form a bead on the backside. Or try epoxy putty and sand smooth.
 
JB Weld. Thick. Rough up the spot. Smash a dab in each hole. Wait till it's almost hard. Use the leftover to judge. Cut the excess with a straight razor. Sand it smooth the next day.
 
I used a close quarter dimpler (the one that uses a rivet puller) and then put MK-319BS rivets in them.
No evidence of distortion from the dimpling.
