Vinyl Roof Adhesive

Folks,

I need your recommendation for vinyl roof adhesive, I have heard people really like the 3M product and others hate it. What have you used?

Thanks in Advance

I use 3M 1357 High Performance Contact Cement or 3M Scotchweld 10. The 1357 is a little stronger, the 10 is a little faster drying.

Both are available from https://skygeek.com
