Today at the mechanic I noticed that my outboard bracket is starting to spauld, where the paint is bubbling , is looks like dywall when fixed with fixall and it starts to spauld, and you can scrape the paint off and it turns to dust, he told me to fix I need to take a larger area and strip down to the raw metal , prime and paint, anybody have any experience on this happening to them, I can go by and take a pic, it it will help !
