Build this rim or scrap it?

Today’s jaunt took me past a man cleaning his garage and piling the unwanted items on the curb next to a large sign that proclaimed that all was free.
As I was close enough to home to either carry things home on the bike or return with a wheelbarrow, I stopped to look.
Seeing my bike, he asked if I was interested in some bike parts that had not yet made it to the curb.
Long story short, I came away with some decent pedals, some cleats, a tube in the box, and a Mavic Open Pro 32 h rim.
Got home and looked at the rim. It is in fine shape, but it looks like the PO must have run over a nail and buried it into the rim.
photo follows.
Here’s the question: would you build up this rim?

That depends on if I had another just like it, or could get one, I might consider it. Doesn’t look like the hole goes all the way through, I would just file it smooth, put a dab of RTV silicone in there, then put some hi quality rim tape over it. I doubt you’d have any issues, probably wouldn’t even need the silicone. I hate mismatched rims on a bike, so if I only had that one rim, off to the metal recyclers it would go.

I'd check that the rim is flat. Lay it on a surface you know is flat. Countertop perhaps. I've got a glass dining room table I'd use. Building a wheel from a warped rim is living life the hard way (and doesn't stop when the wheel is built). But I wouldn't give 2nd thought to that nail hole; just make sure the rim tape covers it completely.

Thanks. Back in the days when I cut grass and raked leaves to fund my cycling habit, I ran over a roofing nail and ran it through my Wolber Junior and the Fiamme Red Label to which it was mounted. I pulled out the nail, changed the tire and rode the wheel until the rim got too tweaked to true. That never took long with older soft rims and frequent criteriums.
Sounds like this one will hold up. And there is another one of the same model that I came across a while back, so no worries about un matched rims....

+1 on JB Weld, or PC-7.

I'd use it, too. Wouldn't even bother with filling in the nail hole, as the rim tape has a bigger job spanning the spoke holes.

As long as the rim is straight and true, you're probably fine strength-wise

i suggest relieving stress around the hole by carefully drilling it round. lessens the chance of it cracking, of a sharp edgy bit radiating out
