On the door side, there are 3 areas (shown in the arrows). I just applied Vinylex to the door seal shown with red arrows. That's the part that actually contacts the Shadowline trim and causes the squeaks. You don't have to apply anything to the felt flocking or the larger main rubber door seal.
Hope that helps.
Could not find either product you mentioned however I used Gigaloo and the difference is huge. Virtually silent which suggest I may have missed a spot. Thanks for the advice
