This is the way I always do it, and advise all my "flock?" to do the same. It
results in a light neat part.

First micro the foam, this is imporatant to give a good bond between foam and
glass. Micro should be as dry as can be spread on easily with a squeegee. Scrape
off the excess to leave the foam almost dry but with all the pores filled with
micro. 

Next lay on the glass and carefully arrange it with accurate straight fibre
orientation. This will be easy because the dry micro doesn't grab the glass.
Pour on the resin and spread it quickly and lightly so the resin can soak itself
in. Move the excess about to wet the dry bits.Working steadily wet out the whole
of the glass and squeegee off from the middle using the wedge of excess resin in
front of the squeegee to push any air bubbles out and off the edges. When
satisfied repeat with the next ply of glass.

Finally  an hour or so after finishing go back and carefully inspect to make
sure nothing has moved. You may find a few air bubbles have sneaked up on you.
Rectify before cure.

Pouring or brushing resin onto a microed foam surface will serve only to spread
micro into the glass skin, not at all where it's wanted
 and grab the glass, making it very hard to get all the fibres laying where you
want them.
