Buy a bottle of the Testors liquid glue for plastic models. Works very well, practice your technique on some scrap plastic first! Dedicate a few different size paint brushes to use with the glue. Bonds (melts) the parts together, start off using a little and find out what works best for each assembly. It is VERY thin and can run, so be careful how you hold the parts while gluing them together. Most top model builders use this type of glue, along with specialty water based white glues for clear parts and assorted CA glues when appropriate (or necessary).
***** BE SURE TO HAVE GOOD VENTILATION WHEN USING THESE TYPES OF GLUES !!! *****
Give it a shot, it's cheap enough and may just do the trick for you. You may also find similar products depending upon where you shop.
Good luck, hope this helps you out. -- Ernie :>)
