    Do you have any pictures you can post? I'm replacing the skylight in my chalet but it's the rectangular one, it seems like you are replacing a square skylight?

    ours is square, and my choice of sizes in clear was very limited. The new one arrives July 30 +/-, and I ain't removing the old one until the new skylight is on the premises.

    Photos are existing details visible today while I wait for the new skylight. The hard part will be removing all the Eternabond sealing tape that the dealer put around the outside of the existing vent. Even with an electric heat gun its a PITA.

    The garnish screws were replaced with raised hear S/S #10 x 3/4" screws. In the garnish, the screw locations were drilled out larger.

    the replacement skylight arrived (and it was in a robust box). It's only 0.08" thick, which seems "cheesy". It did come with a tube of sealant. No screws were included (nor expected).

    Removal process - but half the Eternabond is still in place and all residue is still in place. A simple hair dryer was used to soften the Eternabond adhesive - a true heat gun is fat too hot - it just melts the Eternabond tape. A spackling tool was used to break the bond between Aliner roof and flange of skylight - after my sharp utility knife had cut thru the original caulking layers at the edge of the flange.

    Interestingly - the original skylight had no screws at all (our new skylight has lots of screw holes). And the old skylight thickness seems to be the same as the new one. And its only single pane.

    the original adhesive-sealant between the old skylight's flange and roof is the orange looking stuff - now quite hard. Other than abrasion and chipping, and suggestions on how to remove it. Especially remove it from the old skylight.

    BTW - we are thinking of using the old skylight as a temporary cover above (outside of ) the new skylight. It will keep the inside cooler during the day, and it will protect the clear skylight from debris scratches during travel. We have not decided on the method of temporary attachment yet. The two skylights nest together quite well.

    the yellow adhesive-glue is hard to sand off - using #100 grit paper on a 1/4 sheet sander, the glue seems harder than the aluminum skin on the Aliner's roof!

    And to add insult to injury the "handle" on the end of one of the wire paper clamps on my Craftsman sander broke of - no parts available. So buy a new on (which will be Ryobi 18V One Plus)

    This guy used an abrasive pad attachment for a drill, which he used on his orbital sander: .

    He links to amazon in the description, but here it is: https://www.amazon.com/gp/product/B07RL51TXL?psc=1

    I need to go gently - else I will eat up the aluminum. There is far more control with a palm sander.

    Done up to a point - the new "light" (as they say in the window trade) is screwed and glued. Eternabond tape to follow later in order to hide the screw heads. The sealant is actually 100% as-is - it won't leak.

    the hardest part was dealing with little wisps of sealant getting onto the viewing surface of the skylight - it cleans off with Turpentine (at least, it does when not yet cured).

    the dome weighs the same as the old one - same thickness and same size.
    The old dome weight s2.28 Lbs - which includes some residual Eternabond adhesive and some residual 2003 roof adhesive (the yellow stuff).

    Almost complete, the 4" wide Eternabond tape on the clear window is not yet in place, nor is the Eternabond partial width tape on the old skylight flanges in place (to hide the grey adhesive). In the photo, the old skylight dome is in place to cover and protect the clear dome (which will likely be any time that we are not in bed, looking at the night sky through the clear skylight). In practice, two bungees will be used to hold the cover in place.

    Update - this is a big winner, we both love looking at the night sky and the kerjillions of stars. Its also great foe viewing lightning during thunderstorms.
