An old body guy suggested I use the adhesive to put patch panels in place. I used the double tube with the applicator tool - expensive but it worked great. Patched from the inside then applied bondo for the edges.

Came out great: http://fernscountrystore.com/wp-content/uploads/2012/12/Bella.jpg

Bill is right about needing extra nozzles and the shelf life on the products.
