fixing rust on cars

Surface rust? Sand back to bright metal, treat with a rust converter, wipe clean, then lay down a quality epoxy primer, a skim of filler if needed, colour coat, and clear.

Scale or perforation? Cut out to clean steel and weld in a patch; anything else is just putting lipstick on a land crab.

Mask generously, keep dust out of seams, and wear PPE—gloves, eye protection, and a respirator—because lungs aren’t optional extras.

DIY bits will run about $80–$300; a pro repair is typically $300–$1,200+ per panel, and structural rust is a roadworthy fail, not a weekend hobby.

Seal both sides, wax the cavities, and clear the drains unless you enjoy watching your car quietly turn back into iron filings.
