You can try Soundown out of Marblehead., Ma 800-359-1036 web site Soundown - peace and quiet for architectural, marine, & industrial applications have quite a bit of gasket material
No, it goes between the frame and the actual opening part of the window.
It has a profile to it, Better pics to come.
Thanks for the leads guys but still no luck for me on an exact fit.
But I'm questioning whether I need an exact fit, it's basically two flat surfaces sealing but I don't really want to experiment with this multiple times.
Anyone know of a stick on sealing strip that might work??? Has to go on aluminum frame.
Any other help before I bite the Diamond Seaglaze bullet would be appreciated.
