I used my rage gold tonight and it is not as fresh in the one gallon can before you mix it as it was when I bought it. It worked fine and is only about a month old. I was just wondering how long it lasts before it dries out and is junk and if I can thin it to prevent this??? I am putting the lid back on tight with a plastic hammer and keeping the lip clean. Thanks for any tips, Zach

im by no means an expert at car repair but i do use a lot of bondo in my job. when it starts getting a little stiff i always cut it with fiberglass resin. but then again its not going on a car. if this is a problem for panel repair im sure someone will chime in. HTH- DAVE
