Car Upholstery: Motor home interior repair., spray glue, contact cement

Question
I have an older motor home.  The cealing padded cover has come unglued with time.  It does not have old foam rubber backing that some times drys up and falls apart.  Its clean material that can be reglued to fiberwood roof.

Is there a spray glue I could use or would I have to remove the white cealing cover and reglue it by brush?  What kind of glue would be good to use that would stay up in the hot summer heat.

Thanks for your help.

Answer
A good quality trim adhesive will do fine. Let both sides tack (get sticky) then press firmly and evenly with the flat palm of your hand in long strokes to join the two sides. Contact cement works even better but it requires brushing on. Hope this helps. Mark.
