Mounting soft-bodied specimen (particularly arachnida)

First, Id like to say I'm happy to see an insect forum that is moderately active. I can't even find a facebook group that is very active, particularly geared towards the collection of insects and specimen (I realize that isn't the primary intent of this forum either, but I'd be very grateful to receive a recommendation).I have a quick question that is driving me insane concerning the mounting of spiders for collection and study.

I see it is almost unanimously suggested to preserve these creatures as wet specimen, but I have seen a couple examples (Oliver Greer collection at the Santa Fe Children's Museum, for instance) of arachnid specimen mounted on pins like normal. I am very committed to finding a way to make this work without shrivel or rotting, and was hoping someone here might have an idea or a helpful suggestion of where to look for my answer. I have contacted a couple collectors but am still awaiting responses. Any pertinent information is appreciated. Thank you!

Added to Books
I've added the article to Books(1) under "Mounting & Preservation of Specimens". I'll try it out on some scale insects that have given be some trouble. HMDS does not preserve their color, essentially bleaching them white upon desiccation. The chemicals may be ordered through Amazon.

Dry mounting soft-bodied specimens
was discussed here. I suspect dry-mounted spiders, if successful, would look nice for display but would limit their use for detailed taxonomic study.

 
Acetone inflation
There are specimens for which the abdomen may still shrivel with acetone or HMDS treatment. I suspect many spiders will have that problem. I've recently found a way to prevent this. See paragraph starting, "The rest of the images ...".
