took two sets of neodinium magnets and two metle plates.
put the coat on a person put the plates at the bottom of the hood while it was lying down and put clear scotch tape over them to hold in place temporarily.
then i took the magnets and placed them on the inside of the coat and matched the location of the plates, then taped them in. once i made sure this was the right place for the magnets and plates i took matte black duct tape and went over the plates and the magnets. with matte black you cant see the tape but its still there.
just tested it by standing up in the back of a truck backwards while it was going about 40, and the hood didnt come up. but when its still easy to put the hood up with my hands
