lacougar

Hello All! This is my first post in CCCA. I'm currently working on my first restoration job and have been on YouTube a ton. I've tried anything from white vinegar to CLR (works way better). But I'm turning to the pros at this particular time hoping your guidance will help speed up my work. Does anyone have tips the fastest way to remove rust off the roof of the Cougar? I also included a few images to show the my progress thus far. Thanks in advance!
