As an aside, be sure to wipe down any fresh glass with acetone prior to
sanding. That removes the blush and insures that overcoats will adhere.

A good source of information about glass and what to put over it can be
found in the publications from the West System people. Many of their
publications are free.

Thanks I'll be sure to do that. The resin I'm using is low blushing
but you can never be too safe in these things.
