On my 72 I have several places where the diamond patterned vinyl has lifted up. any tried and true materials recommendations for resealing?

Sorry for the lousy pic post positioning.

 Any good contact adhesive will work.

Followed up on Mark's comment and found another poster a while back using Weldwood Contact Cement by Dap for interior applications. The 3oz. can for 12 bucks has a brush applicator. Also saw a pint of the same product for about 20 dollars. Both have great reviews. can also be thinned with acetone if desired.
