Siding (Filon?) Siging Delamination

[Racing_Roamer]

I have a 2007 Hyperlite Nitrous 19 foot toy hauler.
The siding, right above the generator has become seperated (bubbled) from the body. When I drive, the wind would catch a foot long lip and pull it away from the corner trim.
Is this material called "Filon"?
What can I use to re-attach it?
I saw some stuff called SLV Resin, but I'd rather not spend $150.

Was hoping I could just roll to Home Depot, pick up some sort of Liquid Nail and attach a tube to caulking gun to get way in there..

The total area is about 2 feet by 4 feet.

Thanks

Be sure to do some surface prep so you have a fairly smooth finish. I'm assuming you can't take the panel off completely though. If you have a wall you can probably use a piece of plywood and some compression clamps to hold the filon/glue flat with the plywood as it sets.

If $150 fixes the problem, go spend another hundred on Lotto.

You can use a 2 party epoxy system. You will have to inject it into the delaminated area.
The trick will be to make some sort of clamping mechanisms to hold siding in place as the epoxy cures.
