I suggested using expanded polyurethane foam to seal the roof cavity between the metal skin, the roof liner, and the new skylight. In my personal experience, this gives 3 advantages: 1) it permanently holds everything in place; 2) it provides fabulous insulation both summer and winter; 3) it gets rid of the condensation problem as there's nowhere for moist warm air (your breath) to condense against the cold roof skin. ⚠️ BE WARNED - you absolutely must ensure you use the waterproof version. Some versions are like a sponge if the outer surface is broken (and a roof area full of water would be extremely dangerous in affecting the stability). The expanding foam you need is one that forms a "closed cell" structure. Be absolutely certain that this is what you've purchased. Run some tests by cutting it and immersing into water. In any case, you'll need to practise so you are certain of the expansion rate, else you'll find the stuff foaming out everywhere, and it's difficult to remove spillage. The rule is "less is more", so fill the gap in stages.
Cardboard spacers (vs expanded polystyrene) weren't a good idea. The air gap inside Defender roof liners is a condensation trap. Moisture in your respiration hits the cold outside roof skin, and condenses (typically running down onto the driver's right knee). However, your problem will be when those cardboard spacers turn to pulp... And, by the way, how did you secure the headliner to that skylight? Well secured, the skylight will help protect the lining against sagging.
I think you have a good point there. This cardboard is very hrd and compressed but will collect condensation over time. I think I'll stick to the advice and replace with some polystyrene!
Looks better now, we all cock things up, fair play to you for putting your hands up and rectifying it though. Not sure the cardboard was a good idea though mate😅
Unfortunately the glass has already been bonded into the frame so I was unable to use clamps on the second fit. But weighting the unit down onto the roof skin with the disc brakes worked a treat.
So good to see a channel that highlights that a mistake was made by them and how to fix it. 👍

That looks a lot better. Thanks for the update.

Agree 100%, I would of used rubber spacers for sure.

Great that you keep it so real world .keep up the great work
Good simple fix looks a lot better!

yep, think I'll replace that with some polystyrene!
Good on you mate!
Where were the 4 clamps?

Have you fitted the mudstuff console back in ?
What a bodge way to fit a sunroof, there should be a proper spacer for the headliner.
Yep, I had to do it all again. Chjeck out the other video.
