Sorry for a little late reply, but as Denturepropgh said, I'm really not here to pick a fight. I'm trying to point out that there really are no real answers. There are researches that say monomer passes through any glove within seconds and encapsulates inside them, making glove use worse than not using them. Then there are researches pointing at other results. And then there are people who say they know people who do this or that and that is the right way to go.
At the moment I use those silicone brushes for repairs/relines and for packing I use Ansell nitrile gloves that used to have a classification for monomer resistance, but now that has gone missing from their product sheet. Maybe that really tells that even manufacturers don't really have answers or knowledge of their products.
Since monomer absorbs to skin very fast, I don't believe soap and water afterwards really makes a difference though. Sure, for common hygiene especially at times like these, that is a good habit though.
We did some tests some years ago by putting on different gloves and dipping a finder into monomer liquid for a second. After removing glove, the smell was easily noticed on finger tip, we though this was enough to ensure us to avoid using gloves. This was our own testing, not in any way scientific. But that was our way of using common sense
