My interior roof lining is coming off. Any suggestions with what type of glue may be used to reaply (and where to purchase)?

I cleaned the lining on my '96 RAM a couple years ago (w/ rug cleaner attachment) and it seems to have caused the lining to come loose

 

I have no experience with this but have used 3-M brand of spray contact adhesive with good results. A light coat on both surfaces, let dry 'til tacky, then stick the liner back on.

 

Well i took your advice and stopped at advanced auto for some spray adhesive...
Just got inside from completing the job - it worked and looks GREAT!!!! other than one or two small flaws on my part (stretching the material at the end to the edge, but don't really notice it unless really looking).
Thanks for the insightful suggestion!!!
