i know there are quite a few Eurothane afficianato's here, so let me bounce this question off of ya'll. A couple months ago, i bought a quart of Omni clear & corresponding hardner (don't ask..) but i have used this clear about 5 times, and i followed the basic rule of thumb about cleaning the cap and pour spout off of the hardner, making sure the cap is on tight, and doing it quickly so i don't expose the hardner to any more air then needed, i also stored it in a air tight freezer bag, and stored it away in a dark, room temp drawer, but my stupid harder STILL dried out. Is there ANY way, or maybe something i might be doing, that is causing the hardner to prematurely go bad?? I have been told by a couple paint guys that once you open the hardner, you are S.O.L. is this true?? any sugestions?? i hate to keep spending money on hardner if i can do SOMETHING, ANYTHING to prolong the life of my hardner. BTW, this also happend to my martin senoir eurothane as well. Thanks so much in advance!! chris coffey
