Got my two boxes of TMI carpet for the '69 today. Just got done spending five hours gluing it all in. Still somewhat high from glue fumes. This is the last piece needed to finish the restoration effort on the '69. Gus is a happy VW now!
Used about 1.75 quarts of DAP Weldwood Contact Cement and two 3" cheapie brushes from Lowes.
I got the "Salt and Pepper" carpet from Kustom1 Warehouse (which is close to the OEM grey that was in the car before). Here are a few pics:
Here's the back section and sills in. The glue is down for the front section. (By the way, that's original equipment red basketweave upholstery you see there).
