I recently order the iron remover and it just came today in the mail.. I hoped it would have gotten here a few days earlier because it was really nice here and these past few days it has been rainy and very cold. I had planned on using iron remover, wash, clay, then paint seal my car for winter. I didn't have the IR the day i did everything else so i just skipped that step. I didn't know if i could use Iron Remover on the car now that i paint sealed it. I didn't know if once i sprayed it on there with the paint sealed it would strip it or do something else to it.. I don't want that to happen because it took me a really long time to seal my whole car lol. It was the first time I've ever done it before. I actually did a really nice job. Too bad it's rainy here these past few days but even in the rain.. it's still glossy.. so far. Any help on this question is appreciated. I'm not planning on using it until i hear from people. Maybe i will wait til spring time to use it if it's a bad thing to do for the paint sealant. Thanks.
