For years I have kept an old two literpop bottle in the shop with the lid modified for adding a plastic tube. When ever I use varnish or laquar I put some vinegar and baking soda in the two liter jar and stick the hose in the varnish/laquar can to let the carbon dioxide fill the gap before putting the lid back on. Carbon dioxide is heavier than oxygen so it will stay in the can long enough to get the lid back on. Just remember to not use so much vinegar that the actual foam goes into the can. :idunno:RGriffith said:From what I understand, the best way to avoid this problem is by displacing the oxygen in the bottle with CO2. Some of the woodworking companies sell spray bottles that you are supposed to spray into the mouth of the bottle or can as you are closing it, leaving a cap of carbon dioxide in the container. I have never tried this personally, but have read good reviews of the stuff! :idunno:
