I actually use it with any glassing I perform.
It's just more ideally suited to the very lightweight finishing cloth IMO, due to the ease with which you can distort and or cause it to wrinkle when using the squeegee method.
I also have very little cleanup to do once the process is finished.
Also, once the cloth is down ,cured and sanded, you can use the same method to fill the weave so that all that's required is a light wet sanding prior to prime and paint. The second application doesn't add much and the epoxy flows out nice and smooth.
