DeathProof! That video is a classic. I still pack my kit tote this way. Haven’t seen him around here in a while. His WIP thread is also awesome. He had another video showing the steps he uses to get suited up.
Not a "care" tip per se, but a good preventative measure that I have used before to give a helmet more strenght especially in the mandible area:
glue or putty in a bent to shape metal band that connects the mandibles, far enough away from the visor to still allow for a quick change and obviously close enough so that you can still easily get it past your nose.
