IIRC,  all the slides I've checked w/ FECO show variation in  
"flatness" of only a few microns, However, bend easily to much more.

I've used RTVR (silicone); is its compliance too much, or is the  
advantage the five or 30 minutes?

bc who discovered even water reduces the strength of PMMA (Perspex /  
Lucite)
