Progress Report:
Well finally got the last of the residue off today. Most of it anyway. Probably about 98% clean. Still a few nooks & crannies that have some glue residue remaining.
Don't believe that'll create any problem. Took me 4 days working about 4-5 hr per day to get the factory insulation out.
Took me almost a week to remove the glue residue. That's because we hit triple digit temps about a week ago. It's been 108-112 every day.
So I could only work until about 10-11 a.m. By then the heat and the smell of the turpentine, started getting to me so I'd call it a day after working only 2 hrs or so.
There was very little wind to blow away the fumes and after only an hr or so I'd start getting a headache from the fumes. So I'd quit.

Below left is the stripped cab with the drivers side (upper part of photo) still covered with "Dynamat." Passenger side (lower half of photo) still has factory insulation in place.
Right photo is with all of the "Dynamat" removed and factory insulation removed from passenger side.







Below left is the drivers side after clean up. If you look closely, you can see some residue here and there. Not enough to cause any problems. (I hope)
On the right is the back half of the cab. This is where the speaker box will go when complete.




Tomorrow I'll start installing the first of 2 layers of "Damplifier Pro" The foil and rubber insulator similar to "Dynamat extreme."
When that's finished I'll spray on 4-5 coats of "Firewall" a heat and noise insulation.
The final layer will be a 3/8" thick closed cell vinyl/rubber foam called "Overkill."
If the heat doesn't let up I figure this phase will take me 2 or 3 to possibly 4 weeks. We'll see.
