When I patched the blue deer and after the side was really foamed up I tried and experiment to compress the foam and make a denser patch.
About 30 minutes after I foamed the shot up area I patted the plastic above the foam with my rubber gloved hand, at about this stage.
The foam collapsed back into itself and made a very dense patch. I was completely out of foam at this point and couldn't cover the ragged patch with another squirt to bring the contours back out to the normal level but here is what I ended up with. I have painted the deer but you can see the dense patch. This is my first try at condensing the foam but I may be on to something.
