I applied 303 on all the plastic and rubber trim on my truck twice this month. I applied it with a mf pad, let the 303 penetrate for 5-10 minutes and then buffed off with another mf towel. It has been raining in NJ for the past 4 days and I can see streaks of 303 film on the black paint. Its definitely the 303 running off the trim because the areas of film on the paint are below the trim. GOod thing the paint is protected with Klasse SG so its actually easy to remove. My question is it normal for 303 to run off the trim and leave streaks of film on the paint after a rainstorm?
