>>5947419TIII anon here and I can't recommend it, especially on the TII. Blue paint they used on the 'chin' might melt/smudge a bit if heated up.
Actually cut through the PVC pretty easy if I remember right, so softening it up; might up the chances of cutting too deep into the 'chin' pieces.
Hope it helps, and look forward to see your chin-liberated Tallgeese here soon!
