Replying to Waterproofing

hey guys and girls. i went out today in my orage vibe ht 2 jacket today, shoveled the driveway and jibbed my backyard a little while it was snowing. when i came in, my jacket was a little wet. it wasnt soggey but it did let in a little water. i think my jacket has 3000 mm water proofing but im not sure. i was wondering if products like nikwax and revivex will add to the water proofing or if they will just repel the water and still let some through. i just want my jacket to be more water proof and i dont want to get another jacket. thanks
