Loctite actually makes a 'plastic' thread lock. I bought some just to try out. I think its supposed to be for plastic to plastic apps, but ive used it on a couple screws just to see how it goes. So far so good, but we'll see. My suspision is thats its just glorified clear nail polish but im not sure. Its real sticky, and it says to use nail polish remover to get it off. Go figure.
