moonroof vs. sunroof
moonroof vs. sunroof
there's little difference between Sunroofs and Moonroofs, that's why moonroofs are often refered to as sunroofs.
Sunroofs use metal and plexy and are often painted if not tinted. Non motorized sunroofs could only be used for venting only because you could only operate them like the ones on school buses.
Moonroofs are made of either plexy or glass but they have a sliding piece of material made to match the headliner, or another light filtering material (often black with tiny holes in it).
As for problems, there is a $h#t load of problems with the mechanisms for sunroofs, the plastic gears break more often because there is a lot more weight to pull/push/slide. Glass is easier to work with, replace and find parts that fit.
Fixing sunroof/moonroof mechanisms ain't rocket science but takes time and patience. Make sure the seals fit tight when you get it in, the tigher the better;
I'd also prime and repaint the cut outs, paint peels on heat (from the cut often). What I did with mine is that I left 1/2 inch extra and made the cut out smaller, so I can bend the 1/2inside. The reason for that is to make better seal with the rubber.
Hope this helps.
