Like Matt, I am having exceptional results with silkspan. I use polycryllic versus dope with two coats of primer sanded almost all the way back. My paint and clear of choice is House of Kolor.
The great thing about silkspan is it looks like it came out of a mold. The problem with glass is sooner or later the weave telegraphs to the surface.
I did the Evolaris on the cover of the June issue of the K-Factor using silkspan.
