Sill corrosion
Symptoms
Outer sills bubble and perforate. In severe cases, the car sags and doors bind.
Cause
Stone chips compromise the paint, water sits in the sill box sections, drain holes block.
Fix
Cut out the rot, weld in new metal.
Replacement outer sill panels are available.
Inner sill repair is more involved.
Budget $2,000-5,000 AUD for professional sill repairs on both sides.
