If I remember correctly isopropyl alcohol and denatured alcohol are two different beasts. Isopropyl is what is commonly used for cleaning acrylic.
Regardless, you have more or less chemically "melted" the surface of the plastic, and no amount of buffing, micro mesh, etc. is going to bring it back.
The only possible way you might
be able to fix it is if you can get the lens out and lay it in on a horizontal surface. Buy some FUTURE brand floor "wax". It is liquid acrylic - the same polymer, more or less - that the lens is made from.
Mask the edges of the lens so it cannot puddle underneath, then apply a thin
coating. An eye dropper is an ideal tool to use as an applicator. Let it sit for 24 hours to completely dry, you may need to repeat this. If you're lucky it will bond with the lens surface and restore the optical characteristics.
If you've used any wax or buffing compound on the lens already you'll need to thoroughly clean it off with isopropyl first.
Good luck Jim, and if you or any members of your Impossible Mission force are killed or captured, the Secretary will disavow all knowledge. This reply will self destruct in 5 seconds.
