Dynamat Lite and Dynalite install
I had planed on doing this all along, but was nice to find a thread on others' work. Moondoggie's install is very similar to mine, looks like we made some of the same choices for where to place it. I plan to be a bit more..uh, creative...and extensive with the dynamat. Any remaining scraps will be placed up in the firewall and underdash area. This may irk any pesky review at a later date, but decades ago I found that this stuff is GREAT and the more of it the better...excepting the added weight.
What I did...
Clear sealed a number of seams around the floor and dash areas. (Looks white initially). Some of the sand from the blasting may be encapsulated under it, and this would be an additional barrier to moisture penetration, etc. If someone wishes to re-blast / re-dip the car in 2050, go for it. This should help get it there and beyond.
Dynamat lite (blue) around floor pans, sometimes doubling or tripling up in the structural / indents / stiffeners in the floor to level the floor a bit more. I'm trying to punch holes in all areas where carpet posts should be, but finding this to be a real bear. Already know I've work around for console holes and for driver's side carpet posts, which I need to go back and find. Worst case, crawl under car and poke through.
Dynalite (1/4") over firewall / clutch / trans to shift area. Easier to work with this, even though thick, will stretch compared to the tar stuff (blue). I can tell that this stuff will be good. Whether its temperature claims will be met is another issue. Also curious if the adhesive will withstand the high temp. Again, it claims ability. Will run it into underdash to replace the foam sisal / wool padding which was removed. I have some, and could aesthetically cover some of the newer stuff for period appearance.
NOTE: Heater core area recondition and scuttle vent attach using both materials a bit more creatively. Will post on that soon.
