Fast forward to the replacement roof install. The front section of the truck roof was removed in the same fashion. A cut was made on the roof pillar below the roof line. Then the donor panel was fitted to the cab. The pillar area was then properly fitted to the cab itself. The underneath of the roof was then prepped, & painted before the install happened.

The decision was made to use panelbond to attach the roof back on. They used 3M 8115 Panelbond . When you strip the cab pillar area down you’ll see where the factory joined the roof and pillar section. This is where you want to make the cut. If I remember right, this area was originally leaded in. I’ll confirm how they made this transition & update this procedure if needed.

Panelbond was applied to the cab & then the perimeter of the roof was clamped down. The 3M material will come through the holes that were originally drilled through the donor roof & a second layer of panelbond was applied in a seam sealer fashion to cover the holes & give a factory appearance. This stuff is rock solid & the common roof rust issue will be put to bed forever!

Panelbond was used across the front of the cab and where the factory leaded the pillar joint.

Here you can see that the underside of the roof was totally finished ahead of time. This made for a much cleaner& easier way to bring this truck back to its former glory.

The new skin is now on the truck & it’s ready to be finished. This method seems so much easier when you really don’t want to tear apart & refinish the whole cab.

One last shot of the upper windshield flange that has been smoothed out & ready for paint. I do believe that the panelbond material was used in this area & dressed up to what you see here.

All ready to paint. Now get out there & let’s get rid of those rusty roofs on your favorite trucks!
