Where can I get a jacket waterproof sealed?

I have a ski patrol jacket that has a cross and a patch sewed on it and it was never sealed. It is a great NorthFace jacket but I get soaked when it rains. Does anyone have a good place to get it sealed?
Thanks

like shoe/boot spray on water seal? would that work?

i know nothing about the subject, just throwing it out there.

No it is waterproofed but the problem is where the patches were sewn on it soaks right through. I need the inside of the jacket sealed with like tape or something on the stitching.

try a local shoe maker/repair place…they’re usually pretty good with that stuff

Might give this a try?

Sweet thanks, it looks like it is available right in Hamburg so i am going to try it.

they should have it at ems if they don’t at the hamburg store

any kind of tailor/alterations shop will be able to do this.
