Bobchad,
No, I used a truck bed liner type stuff, like 69MyWay, my floor was in real good condition, in fact the factory stuff looked yeal good, they(factory) just didn't put the stuff on the firewall, or the trans tunnel.
I finished the passenger side, and wow this stuff works, I used 3m adhiesive to hold it down, but for the most part the reflectex holds it's shape real well and I taped the seams like you said and I have had no problems. I did not get to the cargo area today but I did coat it real well with the bed liner stuff. It should be dry by tomorrow, so I can do the back.
how big was your roll? It seems like mine is going to cover the whole car, maybe thats why yours was near $11 and mine was $17, eather way It seems to be worth it's wait in gold. If this works as well as it seems we're going to be in good shape come summer!!
Where are you near in GA. I was there in the military (Hunter Army Air Force) in Savannah, and I spent some time in Ft. Polk near there also.
To me Ga is the most Beautiful Country I have ever been. I also spent quite a bit of time in Moultry (sp) near Valadosta (SP) I could have stayed there forever.
