Are you saying that you removed the window from the trailer opening, cleaned and replaced the seal, reinstalled the window and it's still leaking? The "leak" may not be from the glass/FILON installation, but from some other location on the window asssembly. What type of leak and where is it coming from and under what conditions do you see the leak ???

This is an excellent seal for windows:

Once done, use an RV rated sealant (pro seal/pro flex) on the top and sides.
