Superglue from the local CVS or RiteAid for all small seams and small parts. I use the Testors liq cement for long, straight seams for durability, with drops of CA in between. White glue or really tiny drops of CA for clear parts. If you're glueing (gluing?) on a canopy with CA, it's helpful to have some source of air blowing by on the inside to avoid the frosting effect. ie, if the cockpit is accessible from the wheel well or something, I'll point a fan at it until I'm sure the CA is dry.
