laminating air bubbels

just glased a board and while glassing i recognized that some air bubbles always stayed at some places i guess i didn´t clean up the blank good enough and there was something on it. well what can i do to get these bubbles out after the resin has dried out?is there anything i can do?

cheers clemens

You can use a new razor blade and cut small slits into the glass over the bubbles. Then mix some resin with 20% styrene, catalyze it and paint it into the slits with a small paint brush, working it in until the void is filled. This method works on small bubbles and on lifted areas (like under rice paper). Doug
