i would make a plastic sluge out of acetone and pvc shavings, heres the write up i used,
1. heres all the tools youll need, make sure the pipe you use is ABS plastic not PVC
2. making abs shavings took several attempts the drill worked best...i have actually used my router cut the pipe long ways and run the router down the side a few times
3. put it in a bottle those cheap ones at walmart.. for ketchup or mustard.. then add acetone not much at all as it melts the abs you get a type of glue.. for welding abs to abs.... when you apply it the acetone melts both surfaces but when it evaporates it only leaves abs so you now have a solid piece of abs welded together get it?
you just squirt it where you want it like glue... no you can't use a brush it will just get messy.. and the consitancy depends on how much acetone you put in in.. I wouldn't suggest a very watery mixture then your sludge will just fall bewteeen the cracks.. I make it about the consistancy of.. I can't think.. a little thinner than honey.. that way it sticks where you want it to..
sorry to jack your thread just thought this would a better way to acheive the results your looking for instead of haveing to redo it an a few years
