I too am new to using BVM Aeropoxy and had a strange experience. I was using a new tube of Aeropoxy to create a fillet between a wood bulkhead and fiberglass on my F-16. I used the three inch mixing tube and everything seemed fine. However.........I created a fillet all the way around the bulkhead, about twenty inches total. Now the wierd part; after 18 hours of cure time I went to check the fillet. A three inch section that I had applied about half way through the job hadn't cured at all! I waited two more days and still no change at all. Eventually (ONE WHOLE WEEK LATER) I scraped out the white goop and applied a new fillet to the area and it cured in the normal time. I've read on RCU that its best to store the unused tubes in the freezer, so I did that before I opened the tube. Any thoughts or similar experiences out there? I've since had no other problems with the stuff, but my experience with Aeropoxy is currently restricted to only two jets.

I have seen this. If you have used either the glue or the mixing tube before a small bit of cured glue can plug one side of the entrance to the mixing tube. After a while it probably cleared out and every thing started to work again. If I use a mixing tube I always squirt a little bit out without the mixing tube to make sure both sides are flowing smoothly, clean the end, add the tube and glue. Also pay attention to how much pressure you are having to use, if it suddenly goes up something may have plugged.
You can pull the interior out of the mixing nozzel and clean it with acetone.
