Today I glued my fabric to the belly pans. I used a heavy duty role on glue called S-18. This product worked very well on my canvas type fabric. This glue would not work very well on a felt type fabric because the fabric would absorb too much of it off the roller. I found this to be the case when I tried to apply the glue to the sound proofing material that goes on the side panels.
A spray on adhesive worked well for the sound proofing fabric. I masked off the outside edges of the sheet metal and sound proofing fabric to counter any over-spray. I removed the masking immediately after spraying on the adhesive.
Below you can see some photos of my setup and results.
