Warm enough in the garage today to install the cowl seal double sided tape. Shouldn't dip much below this temperature over the next two days.
Also purchased a heat gun to help me warm things up. Harbor Freight Christmas special deal, worked well.
This is the gap I want between the top of the cowl seal and the bottom edge of the raised rib on the face of the windshield frame.
I was going to try to use a spacer straight edge, in this case a piece of aluminum angle, to keep the top of the tape perfectly spaced below the rib.
In the end I just free handed the tape install. Too hard to hold the spacer and work the tape at the same time.
I worked slow, got the tape down straight this time.
I preheated the cowl before installing the tape. Just warm, not hot. Rolled the tape down with a socket. It stuck down great. In the picture above, you can actually see where the tape sunk down into the spot weld divot.
After installing the tape I reinstalled the cowl seal. Took about 30 minutes to get the cowl seal exactly how I wanted it. After that, slowly peeled off the backing film from the tape, about 4" at a time, and stuck the face of the cowl seal down as I went.
I rolled the seal down on the tape with a socket. I also used the heat gun and warmed the seal/tape up for about 20 minutes. The seal stuck down to the rubber great this time.
I ran the tape almost to the top of the seal. Pretty happy with this.
I waited 2 hours, then folded the windshield back into its full upright position, installed the bolts, worked the inner face of the seal back straight, and then firmly tightened up the windshield frame to cowl bolts. Pretty happy with the interior view.
Pretty happy with the 3M tape this time around. A few pointers that I learned the hard way.
1) make sure the temperature is above 60, preferably over 65, like the instructions note
2) a heat gun is a useful tool
3) install the tape as straight as possible
4) work the seal to the tape a little bit at a time
5) clean the metal and rubber with 91% Isopropyl alcohol
Glad that ordeal is over. After about two hours that tape seems stuck. The instructions mention 72 hours for 100% cure.
