i think i'd try 'weatherstrip' glue first. it holds through all the usual heat ranges and resists impacts and rubbing / peeling loads very well. it's basically contact cement but 3m often makes superior products.

to optimize the holding power i think you need to coat both clean contact surfaces completely and then mate the parts wet and hold them in place till set. tape might direct the holding pressure more accurately than the window itself which would tend to 'overturn' or displace the wiper.

keeping the strip clean and supple will reduce the loads on the blade.

gorilla glue is urethane i believe and works best on slightly porous surfaces. it hardens properly with available moisture. it's tough but relatively brittle when cured.
