Glad I could give you that extra push! The DEI silicone spray came from advanced auto. I was shocked that a local store actually carried something I needed since I'm used to ordering most stuff online. If you don't spray it, the wrap will fade to a black denim sort of color! I soaked the wrap and wrapped the pipes, and let them sit in my basement all week to dry since it's been rainy here then put 2 coats of the silicone on and let it dry over night then back on the bike. I let the bike idle for about a half hour to cure the spray as the can states 400 degrees to fully cure. It never did smoke like most people say they get when they wrap their pipes, I'm guessing it's more steam than smoke from the wet wraps.
