Has anyone replaced the "sidewall seal" on a Cobra trailer?

This is rubber gasket that runs along the top of the trailer's bottom half side walls and seals it to upper trailer shell. There is also the identical gasket at the front of the trailer which seems much difficult to access short of removing the top.

If you have done this do you have any hints and tricks to share?

Thanks, John DeRosa OHM Ω

I have always added glycerin to the soapy water for both the top and bottom seal. Makes it all a bit easier. Available at pharmacies.
