KOSS HHV-LC refurb questions

I opened myHV1's to use some Deoxit F5 on the fader and discovered issues.
A) - The thin piece of brown foam around the fader turns to dust if touched.
B) - The driver magnets in the nylon housing seems to be plastic "welded" in place.
C) - There is some sort of white debris on the opposite (ear) side that is clearly disintegrating.
------------I tried to get each of these in pics.
My Questions:
# 1 - Does anyone know what the thin foam part is called or where I might find replacements. (image 1)
# 2 - Do I just cut the 'welds' and glue them back- re-weld, or what? (image 2)
# 3 - Any idea what the white stuff is or what I'll need to fix it? (images 3&4)

Thanks very much.

I have already read that page, and reread many parts.
If it answers any of my questions (above) I missed it?
(I'll go read it again)
Thanks very much

OK, I see now the "scrim cloth" is what you put in place of the brown foam.
Do you know if KOSS calls it that too?
I thought scrim cloth was the cloth inside the foam ear pad.
What is that for, do you know? Just to keep dust out?

It's just to keep dust out, but it can change the tone characteristics if the material is thick enough.

The stuff I used was transparent to sound.

I have seen the information you seek regard regarding the plastic welds, removal of the drivers.

I think it was on HeadFi. I'll post it if I can find it. They swap the drivers somehow.
 
Both of my KOSS HV 1 sets are suffering the same issues.
I really appreciate your help.
Do you still ship out the scrim cloth cut-outs?

I'd be glad to ship them, if I can find them.

I made 4 extras, and no one asked for them until now.

Give me a couple of days to search.
