That Plastic Welding System is great stuff, I use it on everything plastic. The only plastic it won't work on is the flexible kind. A word of advice, back all cracks up with a thin piece of plastic or plexiglass glued in with the Plastic Welding System to prevent the cracks from opening again. Take my word on this is as it is from personal experience. That 8 point cage from S&W was the basis of the modified cage in my yellow Hornet. It is well worth the money. "Doc"
