2G Is there a way to stiffen the blitz style polyurethane front bumper 95-99 eclipse

[96WhiteEclipse]

I recently bought a polyurethane front bumper for my 96 eclipse and it’s all over the place. Wobbling everywhere not very rigid. I’m not expecting it to be like an actual body panel but is there a way I can stiffen it and paint it so the paint looks good and it has a tad bit more righty to it?

To keep it visually appealing you could add something to the backside. Like maybe a fiberglass film or something of the sort.
