No Seal Window Sweeps

[71enthusiast]

This is a little write up about my experience with window sweeps.
I have bought these things from different companies and still end up with the same results.
Here is the problem I am having:



I'm looking for a set that actually seal when the window shuts.
All the ones I've used haven't even came close.
This picture is of a brand new door also so there shouldn't be any seperation.
I've used GMCPauls and Classic Industries which both have top quality parts, However this seems to be a problem with me.

If anyone knows where to find some extra thick sweeps, let me know!
