Thinsulate to Metal & Fiberglass - Alternative to 3M 90

Hi All,

I am about to start insulating my Ford Econoline with a Fiberglass High Roof next week, with Thinsulate 3M.

The only recommended adhesive I can see is 3M 90 adhesive spray.

However, it looks like there is a shortage at the moment and the lead time is 1-2 months.

Can anyone recommend another adhesive they have used for this application?

Thanks for the help!

Seems to be available online via Walmart, and possibly via your local Walmart depending on location.


SMB-less as of 02/04/2012. Our savings account is richer, but our adventures are poorer.
