Loctite 3035 quickly moved to the top group of my glue list. I was able to repair a cracked hard plastic in a vulnerable place, that I would have never succeeded in gluing before. I managed to glue neoprene to natural rubber, a combination that I could not tackle before in a satisfactory manner. The leftover glue firmly adhered to the hard PVC leftover package in which I was mixing the glue. I do not think that you need to agonize over any mixing tubes. The plain and simple method worked fine. At first I even progressed without any dispensing gun, but then got a cheap no-name one and it worked fine for me.
