Hi all!..i've build plastic structures and have recently had a couply of structres Loose their walls because platic glue had "dried out" or something. My original glue was "testor's Plastic cement". I have since switched to PLASTRUCT Weld. platic solvent cement and so far no problems...BUT, the reason i write this thread is to get feedback from all on what product you find to be BEST?!....nothing like breaking your but to construct nice model only to have roof pull off when you lift it.....Coments on adheassive for wood structures would also be wellcome as i'm about to try my 1st.....Thanks to all Tom
