Just about anything you put superglue on or mix it with will end up very hard,
as the glue is a cyanoacrylate. I wouldn't be heating it up, as it will release
noxious gases, and sanding it isn't much different from sanding plexiglass or
Unfortunately, acrylics as a class of plastics are all pretty hard and not
flexible at all. I can't imagine anyone using it for a bumper face repair, as
most of those are a much softer type of plastic.
I've had several blocks of superglue left after leaving the bottle in a hot
garage for a while. The stuff is really ***ce it sets up.
Hope this helps a bit...
