My experience parallels this.

I did notice in the link that 'high voltage' and 'critical air free applications' was mentioned. I suspect that the very good vacuum they say is essential is not just removing air it it is removing adsorbed water which is a real no no in materials working with high voltage.

Also recognise that they are trying to convince you to buy their system. A little hyperbole in sales literature is to be expected.
