in the process of restoring my 86 Reliant, both front floors were gone on the sides, and the passenger side had rust up in the higher wheel well.
what my dad and i did, we welded it from the outside so it looks factory. then we used roofing tar to seal it up, and it looks great. the judges cant even tell its been patched ( i show my K with a mirror under the chassis)
the 1988 Aries from florida we recently patched a very small hole not rusted through
the low mileage 85 Aries, Rear rockers and left rear quarter panel. floors are 100 percent solid
