The gluing process is simple.

I use a Plumber's Flux Brush(.25 cents) to brush the glue onto the Rim and Tire.

Let dry to a tack(about 20 minutes)

Assemble the tire and rim.

You should also pre-glue the spare tire so that it is ready when needed.

No Mess. . .

I have never in many years had a tire seperate from the rim during recreational/club riding.
