Much easier than fiddling with a sticky RTV and no risk of getting it on the sprocket when trying to slide the cover between the sprocket and rear crossmember. The seal holes are precisely aligned, the screws will not forcefully rotate and accidentally damage the seal. It's been 24 hours, no leaks yet and in my experience if they were leaking they would have already started. That alone is enough for me to recommend this product, but knowing that it's also recyclable isn't a problem. The tightening diagram is given on the package, follow it and you will be satisfied.
