My Lancair canopy came with Spraylat already on it. It was good stuff but, when painting, you would be wise to cover it with a secondary barrier just to be sure. Mine had a couple of "thin places" that allowed some paint on the canopy. It peeled off easily when the time came.

Brushed it on
 

I didn't read the original post well.

I brushed it on with an old paint brush. I'm sure a small paint roller would work as well.

You're not looking for a perfect coat. Just slather it on.

In fact, looking at the post regarding limited life, I'd cover outside and inside. Then cover it again and again until you've used it all. I expect that extra thickness will make it easier to grab and peel off.
