PVC cement will destroy the plastic on the plane. What you need it cement designed for this type of plastic. The best cement is called IPS Weld-on #4. You can buy small bottles of it at any hobby shop that sells plastic models. If you can't find it at a hobby shop you can go to a glass shop, the type that replace windows. They use it for working with Plexi-glass. You should be able to buy a quart of it. But as you already know, make you leave the lid on it. Transfer a little bit of it in to a smaller bottle to use while working on the plane.
