I have fixed my fork seals using the sealmate tool, on several bikes. They were fixed after I cleaned the dirt out with the tool, then pumped the forks many times to reseal the oil seal. It worked great anytime my forks needed resealing or had something under the seal.
I also used the sealmate tool to reseal my counter shaft sprocket seal.
I was amazed that it resealed the counter shaft sprocket seal too. I am a true believer in resealing those fork seals and counter shaft sprocket seals, or any other lip seal that you need to have resealed.
