I had to strip the interior of carpet and re-install. I used a spray on "contact" glue and it didn't hold very well at all.

So I pulled it all out and next used some spray on "commercial heavy duty" really sticky glue.

... it didn't hold either. Looks like a brush and DAP is up next!

In both above cases at first it looked like it was working well. A few weeks and ENGINE HEAT and the carpet was sagging badly on the sides and under the dash area. The "floor" was fine, after all it hasn't got anywhere to "fall".
