Hi Rye,
Some Pics would help. Are you going to paint this in the end? Is it glass over wood?
Pics of how bad it is now would tell what has to happen next.

There are ath least two types of what people call "Bondo"
A course Bondo (typically used for big dents, mixes to a pinkish-grey color) and a fine finish bondo cream that mixes to a mustard color. The fine finish is used for filling scratches, pinholes in the course Bondo, and works great for filing in the "Grain" of fiberglass cloth.
It is easy to wet sand and produces a smooth finish that takes paint great.
I use a Bondo Squeegee to apply it but a peice of heavy poster paper does a decent job too.
Don't apply too much, try to get it as level/smooth as possible before it sets up.
It has more of a cream consitency than a heavy-dense "Goo" consitency.
Oh and when I say Bondo I mean auto body filler in general as there are lots of brands out there.
Hope this helps...

For future projects mix microbaloons in your top coat of resin and it will be much easier to sand smooth.
1 brush on a thin coat of resin to seal the wood and keep it from sucking the resin out of the glass, let kick but does not have to be hard before going to step 2.
2 Apply glass and wet out just enough to make it all clear but don't try and fill the weave.
3 Apply microbaloon resin mix to fill the weave of the glass.
4 let kick off well then sand to a glass smooth finish.
