What’s the value of this ??

Well see, I'm not going to take chances with something not made for the job. How do you know what that's doing to the inner workings and passages? Not knocking what you're doing, I hope it works out. That would be cool. But there's just no way to know "for sure" since you cannot see it. My rule of thumb is, if it's possible for something to go wrong, it will. lol
I’ve used it before, just a few minutes will strip and have no returns. As far as not for the application POR was patented as an industrial adhesive
