How do you get a DP 95 helmet unwarped? I heated it up and let it cool while holding it in the correct position but in 3 hours it would be back to its old warped position. Also how do I round the top of the helmet?
IIRC, the vinyl in the dome area is just a bit thicker, so it may be harder to knock that out and have it hold its shape. All I could suggest would be to get it really, really hot and gently pull the helmet down over a tall kitchen canister or something and hold it until it cools. Good luck!
