Thomas, thank you for your praise, and Mr. Cryns, thank you for your kindness, your interest and your curiosity!
So, i will try to answer the questions.

Because GS is a better adhesive than, for instance, superglue?
Well, i believe, superglue is an excellent medium if the adhesive surfaces have direct contact and are sufficiently dimensioned. And, not to forget, a sufficient pressure can be applied. But it happens for example, parts must be connected with a little distance. Then i usually put a metal wire with superglue and build a "bridge" over the empty space between the parts with GS. So i have the effect glue as well as volume. This is which was meant with the use of GS as an adhesive. If you can use enough GS, it is even possible to omit the wire. But this is not a recommendation, with wire is always better!

I don't understand this one: GS can be cut but not scraped with a scalpel.
MS can both be cut and scraped. Or is it because MS will crumble more easy when cutting it?
You describe it just right. According to my experience, MS tends to fragmentation during cutting. This is sometimes not disturbing, especially if the areas can possibly also grind well. But sometimes it bothers. In doubt and when i think i need to cut i use GS. I do not know exactly what you describe, if you write, GS could not be scraped. You mean not grind, do you? I guess i work without this scraping technique, otherwise i perhaps would have noticed this too.
Generally i admit i work much less frequently with GS compared to MS.

Very good idea. Doesn't this affect shape an size of the finished parts?
According to my experience, the liquid superglue does not add an additional volume. It seems rather that it will absorbed into the MS and sealed the surface. It's like a thin protective layer, not dissimilar to glazed ceramics. But it's only my experience. However, there is no reason to don't try it out. Maybe it's helpful.

How about the molding? Is there still priming paint on your model or do you remove it before sending it to the factory?
Before i give masters to moulding and casting (whether primed or not), the entire surface is extensively cleaned and polished, with grinding pads of the grain 2000 and 3000 and finally with the foam backside. All what according to this procedure afterwards still adheres on the master, evidently does not go down during the molding. In any case the foundry has never complained so far...
