Trying to remove a dent in a dish

[Likvid]

I have a dish where i try to remove the dent in it but i fail as tried to smooth it out and it's gone but it seems the tension is moving around so if i smooth it out it will come up in another place close to the original spot.

Is there any way to remove a dent safely in a aluminium dish? the dent just seems to move around....

It's stretched the metal.
Is this a solid aluminum or mesh? (I'll take a stab at both)
Solid-Only way I know of "how to shrink metal" is heat and then cool rapidly. Warm it up with a torch, apply a cold wet rag.
Mesh-probably remove the panel. Roll it (or?) to flatten out the imperfections. Would probably have to trim it to fit as this may stretch it some.

I straightened a mesh panel by removing it then laying it on my shop concrete floor with the bent side facing up. I then took a large rubber mallet and proceeded to flatten it out. When I went to reinstall it it worked better upside down instead of like it was when I removed it. This was a panel that was held on with screws on my 7.5ft SAMI dish.

My 10ft Winegard dish has several panels that have extensive hail damage but those are captured in a way that I can't remove them without cutting some metal away on the outer edge of the dish frame and I really don't want to do that. I have pushed some of those hail dents out with my thumb from the back side though.

It's a solid aluminium dish, it's a small one, only 3"

Auto body dolly and hammer might be an alternative but think shrinking will give better results. Dolly and hammer will probably have to be followed up with shrinking
