I had read on a nother thread that if you put ABS in acetone it melts it to a white gloop. Is this the case? If so, does this then harden again after? I have some gaps on my FX helmet which appears to have been put together in a rushed manner. Would this white gloop act as a filler or if not, does anyone have any other suggestions. Where the gaps are you can see the cement also, does not look to good.
