Pretty cool technique to peel the film off of your prepreg! Not sure what it is but it looks like a cold liquid! Does anyone know what this stuff is?

I think it can be ice spray or pressurized air. I am more shocked how they store their prepreg:eek:
Haha I noticed the same thing! Should be stored in sealed plastic bags and thawed out before removing them to prevent condensation on the prepreg.
Using flash tape works well to remove the plastic backing on prepreg
I use a ruler on some to get the backing off. Or the digging mouse technique. Or you can whap it on the edge, some flick it with their finger. I’ve found that various prepregs give more or less trouble with backing removal.
That stuff looks like freeze spray. Never use it for that but if you have to pull up a ply, it’s magic.
You can buy it on Mcmaster or through electronics supply places.
