One tube will be plenty. Also, a Dremel tool with the scotchbrite buff makes it very easy to get the old gasket glue off the window frame. Much easier than using solvents and heavy scraping.
Easy things sometimes, are not good for the long haul.
Double sided tape, on metal "does not" have the holding power of super weatherstrip adhesive.
Try pulling the gasket off the metal after a few of months
when it was installed with the black super weatherstrip adhesive. You will tear the gasket, if you try it.
Installing the same gasket using just the double sided tape, cannot and does not have the same bonding abilities.
After even a couple of years, when the gasket is installed using just the tape, it can easily pull off. Not good.
Adding the super weatherstrip adhesive to just the corners, is ok, but still leaves the rest of the gasket with a weak bond.
If double sided tape was so good for bonding, I am sure the automotive industry would have used it, many years ago.
Our tests proved conclusive, do it with the adhesive completely, and your worries are over for at least 15 to 20 years. Don't use it as we suggest, and you will have a bonding problem.
Gaskets being gaskets, you should still spray every exterior gasket, with "silicone spray" to increase it's longevity. Not only on your Airstream or Argosy, but your cars and trucks as well.
