it works ok. I did it to my gf's soft-shell. it wears off, but I didn't think it did any faster than the covering on my rain jacket. ime only the hardshell is properly waterproof
Trouble with the Hardshell is you end up soaked with sweat as there isn't any breathability. The plus of that jacket is how robust it is. I had a crash in mine that left me off the bike for three months, but the jacket got minimal damage.
