Well depending on what you are after. There are a few foams, the Pillar foam (#08457) which is rigid and Flexible foam (#8463) which is..well....flexible.

The rigid is I assume a "structual" foam that adds rigidity and believe it or not adds to the roll over strength of the roof. The flexible is strictly for sound deadening.

I have to say, I use them both at work in general collision repair replacing the factory rigid and flexible foams used in assembly.

I think they are a neat tool to further improve the sound deadening and rigidity of the body.

I will be using both in my 1948 Chevy pickup after the top chop is completed.

WAIT, WAIT, WAIT! Wasn't there a thread (or three) here just a few weeks ago bashing the use of foam(s) for holding moisture and causing rust? And now it's OK? Hmmm.

I believe that the foams that Brian is talking about are 2 part foams that set real quickly. They are put in pillars and such, where there should normally be no water going.
