I love that stuff.
The silky feel of it!
The sounds of it slithering around. (back when I could hear)
Sweet stuff.
But...
Once the fabric touches the resin - it's stuck.
If it's not stuck exactly where you want ot, you are (really) in trouble.
Because you cannot really move it much.
And you cannot take it back off either - it has a heavy wet blob on it now!
Lay it on right - the first time - every time.
You might can "drape" or roll, but it HAS to be kept straight.
Otherwise, you are going to wish that you had taken up golf instead. :)
So laying the glass on dry sounds interesting...
But how to wet it out?
On a vertical surface too?
Well, glass this thin, might just be able to spray it(?)
HVLP?
