Hi, OK, time for a serious dumb question. I have two boxes of Acraglas-gel. One was opened about about four years ago, but still has most of it remaining. the other has never been opened. Are these still good to use, or do I need to buy new? If new, the same, or how about mike and gilbert's BedRock with the micro beads? I only need enough to do 1 or 2 stocks, at most. And, a quart of marine-tex is not cost effective, in this case. Further, I live in a town so small that THE local store only has four aisles, and does not carry any kind of epoxy. On the other hand, I can go out my back gate and ride a four-wheeler all day, or until I run out of gas. Takes a creditcard, and we ain't got no 7-11. Sooo.... I will be ordering this, if I need to, probabily from Natchez as I need a few other things, also. Thanks in advance. C'ya, John.
