This pumpkin is first painted with flat-black spray paint. It will stick for about 5-6 days after that, it starts to flake off due to the pumpkin giving off moisture. During those 5-6 days it will look really, really evil.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
