I know this sounds weird, but I think I figured out what I've been doing wrong with the Pinecil...
I have two dead tips. The iron itself is fine.
The tips stop working shortly after I clean them using fine grit sandpaper which I know sounds stupid, but I've done stupider things…
Not sure why...
Of the four SE/30's I've recapped different ways, here was my experience...Ultimitely, you have to assess how strong the pads look in contrast to the cap legs.
Twist Method - Carefully applying a little downward pressure as well (never upward) - No damaged pads.
Hot Air - No damaged pads...

should it just be gone, consider it a right of passage...It can be pretty straightforward to get it connected again to where it needs to be with a bodge wire or repair. Here's a great video that can help.
Drumroll please.....
Repaced UE8 fixed it!! Thank you all so much for your help! This was next level repair stuff for somebody who's just done a few recaps in the past.
I see what you mean. I cleaned it off, but yeah, that was still black corrosion. It never endsThe pad does have continuity to UC7 pin2 (VID0).
I will double check. It does seem to boot fine and has sound. Just video problems.
