Found weld through primer at O'Reilly's...
It's not out front. You have to ask for it.
First time I did, dude didn't know what it was and said he didn't have it. Second time I showed him a screenshot and he went right to it lol.
Given that all I want it for is the actual spot weld flanges, I may have over bought a little when I got the case of 6 Seymour cans
I had originally pictured spraying the entire inner side of all the panels .
Then realized I can use normal high temp for anything semi close to the weld, and only need the weld through for the actual weld area. Whoops lol.
Anyway, passenger rear inner is done
Didn't see any reason to grind it smooth and make it pretty, so just hit it lightly and primed it

I welded it a little fast, sort of on purpose, and made it oil can. Then tried using the home made planishing hammer from the scaler on it. It didn't do to bad, And definitely stiffened the panel up.
You can still pop it in or out, but it's much harder to do.

And it's not really a deep one so it's hard to see either way.
Then I switched out to the corner piece that needed modified.
It's ugly as sin, but will get seam sealer smeared all down in it.
Definitely not proud of this piece, but it'll do its job and fits well.

The other side I'm going to try a different method on. I don't like this one.
But it fits and I'm using it lol.
