If you are talking about RC-56 canopy glue I think this is the same stuff. Home Depot use to carry it in the stores but now you have to order it online. I have used this for years. I do most of my building with it. It dries pretty fast too. I have even glassed wing center sections with it using .010 pillow ticking for the glass. I just ordered a bottle about three months ago and am thinking about a new build and haven't even flown my last build yet. Its a sickness I know.

I use a syringe I got from the feed store with the point ground off flat so I don't stick myself. IIRC I use a #18 needle for applying the glue.
