It’s worth a try I guess. Tester’s method is probably the way to go for longest lasting results. But if I had that problem and didn’t already have that product on hand, rather than risking $10 for something I may only need one time, I’d probably just use some super-glue I already have and hope for the best. I purchase 10 one-application tubes of superglue for $1, 10 cents each at my local flea market. One advantage of the super-glue approach is you only need to hold it steady for a few seconds. Trying to hold it steady for 5 minutes by hand might prove difficult, and you’d probably be better off removing the other part from the car and gluing the two together on the bench.
Whichever glue you use, it might well work for a while at least, but in the meantime I’d be checking for a replacement part from a local junk-yard. Auto recycling places often list what cars they have at the moment on their internet sites. When one become available, apply that $10 you saved towards the replacement part.
