Michigan's new expungement law / restoration of gun rights

In 1991, I plead guilty to a felony NSF check charge for one year's unsupervised probation even though I had made full restitution prior to being charged. I didn't realize the career spoiling effect this would have. I was turned down for an important promotion when a background check found this conviction. I was even turned down twice to be a census worker. When I served in the US Coast Guard, I qualified on the range with both an M1 and a 45 caliber pistol. Before and after my military service, I was an active hunter and skeet shooter. and reloader. Once convicted, I sold old of my firearms and paraphernalia. At age 75, I would like to resume my gun-related hobbies, teach my grandsons to use firearms safely, and protect my wife and myself from criminals and other bad actors.
