Many people have developed SEVERE allergic reactions to CA fumes. Use enough and your long term health is at risk. Keeping a small fan lightly blowing accross the build area helps a lot on that or better yet drawing the air and pushing it through a filter. It will also pick some of the dust out of the air. BTW - also sand outdoors if you can. If you don't have enough clamps - buy more. Or slow down just a tad. Have 2 tables going, wing on one and fuse on the other.

If you have to "scrape the excess globs off " you're using too much. Find a smaller applicator of some sort.

Tite Bond II is fine for joining sheets and applying them to framework. Like all other skills it just needs to be learned.
