Well, You must know that you can sand out the scratches, and save the
canopy. However, it may be more work than it's worth.

So long as you are prepared to purchase another, and they are available,
why not experiment.

I've seen scratch remover sold for eyeglasses that I'd try first.
I cannot imagine the torch idea leaving a clear view through the
canopy, and removing the waves is as much work as removing the scratches.
