I'm improving the hood on a previous build. A pet peeve is how the hood loves to fall off and hit the hardest surface around, on the pointiest part. ? Even if you don't make a hinge (in this case not operable but looks real), this trick will be an improvement. Obviously if it's not a '50 Chevy, the placement will need to adapt.
Materials: K&J Magnetics (website on label), steel from something like a coffee can. In this case, I used thick aluminum so it wouldn't be effected by the magnet.
Video demonstrates that I figured out how to make something work.
