When I have to use cement I generally use a good quality head cement or sally hanson, One cement I like is Loon hard head, makes a nice shiny head, and be cut with alcohal. Thinned goop is good for wingcases, also vinal cement. I would stay away from water based glues I think in time they break down in time. CA glue is good if you really need to hold a part in place, but I've seen Ca break down also from being in water....... Years ago we used to take some clear vinal, acetone and mix to make cement in quart jars....... did someone say brain damage?
