My '90 C4 vert vinyl top is coming unglued and curling up at each rear corner. The top otherwise is in great condition, tight, spotless, clean and great window. My question is what adhesive would be best to refasten it? Do I use a adhesion promoter first? Anyone ever heard of H88 adhesive?
Thanks!

Up dated info:
Found 2 products: WELD-ON ®4784 Vinyl Cement and Rhino Glue. Anyone had any experience with these products?

Thanks!
