For aerospace we use a special process. I'm thinking you need to have some sent to you. Very easy and environmentally friendly. You'll want to prep all the metallic parts at the similar time, since once mixed it only last for hours.
In one of your previous posts, you mentioned envelope bagging, this is how you are minimizing air into the joints. Not sure if you realized it or not. Bigger parts become more difficult.
BTW, I still have issues opening those links.
