I bought some 1Z Gummi Pflege a while back on instinct, since I need something for the exterior rubber on the outside windows to try and bring them back and protect them for further UV rays getting to them. Most of the uses I have seen for the Gummi Pflege are where people are using it for door weatherstripping rubber. Does the Gummi Pflege work fine on exterior rubber and seals? I have used 303 in the past, but I didn't like how it'd run all over the place if it got wet. Does this seem to be the case with the 1Z to if moisture gets to it a few days after applying it?
