I have air brushes but do not use them. I buy Testor's and Floquil at garage sales, from the sale counter at hobby shops and train meets. That is my way of holding down the price.
I put new seals on the bottles made from hard clear plastic like that used to come to hold new shirt collars up or from toy or other packaging: Just cut to fit with a scissors. I also store them upside down in a cool place. I have several jars of model airplane dope ( fuel proof lacquer to some) that are over 50 year old, stored upside down and still good.
