A quick digging around on google reveals a chromic/sulphuric acid mix is used to etch plastic prior to plating with metals and other plastic coating.
I had a moment that I thought my chemistry memory had failed me............
A quick wipe over with a flame is much easier :-).
Chromium trioxide apparently. And that is ACIDIC?
Well its an oxidiser certainly.
If you were to make mall holes through the polythene and epoxy on both sides, you might get better holding power
Bonding with a gluey substance, gluey = viscous. Flowable adhesive that can produce a gap-filling, liquid- or gas-tight bond.

How can you define "gluing" as "bonding with a GLUEY substance"? You're using the term (glue) to define itself.It doesn't work that way.
More accurately,it could be "bonding with a sticky substance or 'adhesive'.",and contact adhesives are sticky. They also are "gluey",they flow,too. How do you think the contact adhesive gets onto the object to be bonded? It either gets painted on as a liquid,or sprayed from a can;again-liquid in aerosol form.
It doesn't have to be "gap-filling",either.It just has to adhere between contact points.
You are guilty, literally, of quibbling.
Thats what I said or cant you read.

He can read just fine, and, no, that isn't what you said. You misspelled it. He didn't.

No, I can read, but you can't, and you can't spell either.
Look again. Carefully.

That's typing, not spelling.
Yes, but what window did she come in through?
