i do a lot of styrene fabricating . This stuff works great !. similar to super glue but thicker. it bond's pretty quick and within 30 minutes i can usually work with glued pieces and nothing comes apart. Home Depot is where I got it. I used it to rebuild this missing section of quarter panel on a 74 eldorado. It took 5 pieces of sheet styrene . It sands well too. I use this a lot. got a bunch of fabricating project going on and this stuff works great. In a few hours its not coming apart.
