Help! Stumped by indestructible green adhesive
I want to do a roof raise on my 2003 Thomas rear engine. In order for that to happen, I need to remove the external skin panels from the ribs/pillars between the windows. On my bus, these panels are held on by screws, so I thought it'd be smooth sailing, but it turns out there's also a layer of some green adhesive/epoxy holding them onto the ribs. This stuff does not want to let go!! I got one of them free after much hammering and prying and cursing, but I nearly ruined the second one and had to give up. Is anyone familiar with this green stuff? It's very hard and solid, not gooey or sticky, and amazingly resilient. Any magic tricks to make it budge? I bet I'm not the only mid-aughts Thomas owner who's tried to do a roof raise...

You can try what I did:
I used the air chisel- just lay flat against the panel and BRRRrrrrzzzzt ! It was apart. I re-profiled my chisel edge to be single bevel.
Creative problem solving is a skill that Skoolies help build, that's for sure.

What angle did you attack it from? I tried hammering a flat pry bar (essentially a big chisel blade) between the panel and the rib from below, which worked okay on the first panel (left it a tiny bit bent), but failed the second time (bent the panel more severely and didn't break the adhesive).

Try a heat gun. Worth a shot.

Hmm, now I'm realizing that this is complicated even more by Thomas' signature slanted windows.... I would pretty much have to do the rib extensions *below* the windows, where the ribs are vertical, meaning I'd also have to at least partially remove the whole outer paneling on the sides of the bus....
Edit: Perhaps I could accomplish it by just unscrewing the top of the panels + rub rail and then cutting the ribs very very carefully without actually moving the panels... Need to investigate more in the daytime.

Or just add on to the roof...

angle- air chisel starts into seam at 45 degrees, then lays flatter against panel.
Air chisel is the key word- hundreds of beats per second. It slides the blade between the sheets.
Try hammering putty knife.

You'd get a prime seat for that low bridge

Details, details. We may need a few overpasses made into drawbridges.

I think that truck did a wheelie while the top was crumpling. It's nice how it was shot from so many convenient angles.
We have one tighter than that, also because of a railway bridge in a major rail artery. Some of the parts of our country's infrastructure are just silly. It's like the government doesn't expect to continue living here.

I'm impressed they even have a digital sign that senses your height and lights up OVER HEIGHT MUST TURN before you get to the intersection and it functioned correctly. I hope he got an appropriate running red light ticket after they viewed the video.

It's a panel adhesive to aide in structural integrity and vibration control.

Whatever it is, it's amazing.
I would love to have a list of the exact chemical components that went into our buses manufacture. In particular, the window sealant & that green stuff. No matter how many times we've removed and replaced our windows during deconstruction, they refuse to leak. The always-flexible sealant re-seals with perfection every time. And the green stuff...
What was left on the body panels stayed there when we painted the floor. It got prepped just like the steel did. It had better adhesion to the metal than the paint could ever hope to!
