That's the type stuff many people have succeeded in their aquarium hoods. No glue involved. Screw the channel to hood job done. I have seen similar to above but square profile with transparent plastic sheet insert rather than white as in above.
Not realy cheap, you buy it per weight, smallest pack i could find is 1 kilo at around € 20, You need a few grams to coat the strips. For the rest thats left after it was opened could have a shelf life. Next to that most resins of the shelf are UV sensitive, need an extra added protector. Or else will turn yellow over time. You can not say in a shop i need 4 gram resin and the 10% UV protector. You have to buy it by the lot and mix your self what you need. If the least amount of resin is offered in a kilo, the smallest amount UV protector likely will be 100 gram bottle.any advice on the resin?
