UPDATE: So 4+ years later this quick repair appears exactly the same. The car has seen plenty of miles, salt, and track time with no ill effects. Obviously, if you have a nice/valuable car go get it professionally repaired but I’ve been busy enjoying this crappy Miata!

Let’s fix my beater Miata. Keep in mind this car cost $1000, so no this isn’t a professional repair. However, this video should guide you through the basic process of repairing rusty rocker panels (or sills) on a NA Mazda Miata (Mx-5) or similar vehicles.

    Nice job done 🙂 However, please use gloves when doing this, the metal parts are extremely sharp when brushed dude.

    Great video for a cosmetic repair, , unfortunately this repair will not go thru a UK MOT.

    Repair needs to be continuously seam welded anywhere not originally spot welded.
