Interesting....I'll have to pay closer attention to that when I buy another
set...I know there was definitely something on all the tires I got from the
Shell sets a few months ago....
Are you hands irritated like greasy? or like dried out?? If they're dry,
there's a chance(probably a slim chance) that if the bricks came out of a
sealed bag, that they were still dry...meaning, that ABS is dried before
it's molded and the parts will absorb moisture from the atomsphere after
being molded, so if you're handling dry parts, they will suck the moisture
out of your hands...Now, this is sometihng that someone running a molding
press and pulling parts will see, but I've never imagined that happening
anywhere else, BUT then again, if the parts make it to a sealed bag right
away and you handle lots and lots of them...maybe that could happen...
Again, I'm not saying they don't use mold release...I just doubt they use it
in any large quantities....It does cause other problems and there's not much
of a benefit of using it.....
I was very surprised when I recently found some parts that had "pin-push" on
them (that's when the part sticks in the mold hard enough that the ejector
pins distort the plastic while pushing the parts off the mold)....
