Just remembered I forgot to post this here: Copypaste from the RPF
Proof of concept:
Scour mesh over lycra, with a layer of latex on top.
In this case, I'm using Tulip's "slick" fabric paint.
Elasticity in the red is *significantly* decreased, however... It does still stretch a bit. If this was the raimi suit, I don't think this method would be viable... but since the reds in the Amazing Spiderman are minimal, I think it could work.
At least, I'm going to proceed with some more variations on the technique to see what results/ Improvements I may yield.

The scour mesh was the most accessible to me for testing purposes... However I find that the honeycomb pattern is more or less ideally sized for receiving the latex, whereas a stretch lycra mesh or jersey mesh (being thicker), might appear too dense after a latex coating.
That's just conjecture on my part though, I would still like to test it on a variety of meshes.
On the elasticity: stretch is effected by the absorption of latex into the lycra fabric, it does not have so much to do with the mesh put on top of it.
Like I said though, I could see the correlation between the way they sized the reds and the amount of stretch on the AS Suit as being a problem/solution based off of this technique. Knowing hollywood though, they probably used a custom silicone covering and not just 'latex covered mesh'.
