[RE-wrenches] Silicone on Module Glass

[frenergy]

Benn,

         I would think a phone call or email (to get it in "writing") 
from the manufacturer would be the safest route to take.  I know PV 
glass is no standard issue product and must vary some from manu to 
manu...composition, thickness, texture (or not), coatings?  So I guess 
I'm more concerned about the affect the paint thinner may have on the 
glass, it's surface, a coating?... than its affect for several seconds 
it might be in contact with the glass/frame sealant.  I'll also bet a 
dollar that the sealant is much better than anything we can get.
