Out of what you have there PERL should work very well for that task.
I have used the Gummi (the first I bought for seals when I joined the forums).... It is fine but.... I consider it HIGHLY overrated and expensive compared to the product below...
Duragloss Marine & R/V Protectant #531 provided UV sunscreen protection for gelcoat fiberglass boat and RV finishes.
Weather seals:
Protecting the weather seals of a ragtop vehicle is an important task. The most pressing reason is the sound dampening factor, which tops the list of obvious reasons you should care for your weather seals. When choosing a product for this task I haven’t found a product better than Duragloss 531. A long time ago Jim sent me a sample of this product in an excellent bottle that aids in application. DG 531 has become my go to product on the seals around my top.
