I learned about it here on the forum. psuedopimp was wondering about fixing the broken off mounting ears of radiator shroud, and Grumpy old man gave a couple of youtube links to the super glue and baking soda trick. I have since used it on various plastic repairs and it is pretty incredible. It makes a super tough plastic. I recommend leave it to cure overnight.
