Old Claybusters had all kinds of bent petals. Bag of them in a dryer was one solution. They have since fixed the problem.About 10 years ago I recall a thread about fixing deformed wad petals. I believe someone said they put the wads in a zippered laundry bag and placed the bag in a clothes dryer on a lower heat setting for a couple of minutes and the petals just went back to their corret position. I never did it but I thought it could have worked providing you took the bag out after a few minutes at a lower heat setting.
