I read that vinegar was the best stuff for storing epoxy brushes, that it didnt dry out over time like acetone.

has anyone tried this, does it work, will it be ok even for a "finishing" brush?

Thanks

I have always used acetone on my finishing brushes ( that arnt so cheap) and have found that they do dry out after a month or so even in a sealed jar. The result is a ruined brush and a jar full of jelly that may as well be thrown away too. I understand there are risks involved in this but so far my tests have worked well and i have read of people commonly doing it on boats and surfboards so i thought it was worth a try. The vinegar neutralises the resin the meths cleans off the vingar/resin residue, the meths evaporates and is possibly compatible anyway.....I do use throw away brushes for laminating as im not so concerned about bristle loss but either way throwing away brushes is annoying for me.
