I would give it a try. Set up a small test piece and see how it pulls off and what surface it leaves behind.

Peel pyl is normally a layer of composite material that gets coated with epoxy or in this case polyester resin, with the rest of the lay up. It is the last or top layer. When the resin dries, the peel ply layer doesn't bond to the other composite material and can be peeled off. this leaves behind a surface that can be ideal for bonding on additional composite layers or other composite parts with no additional grinding or extra sanding required. It also leaves a surface that can be easily prepared for finish sanding if the part is going to be primed and painted.

You can use peel ply for polyester resin. If you are doing a large area and you have the choice of light or heavy weight peel ply. Use the heavy weight it is much easier to use.
That's what I found.

I used peel ply to stop the green mesh from sticking to the foam I was vacuum bonding to the hull.(using polyester resin).
