If you need rusty bodywork sorted, it’s well worth getting a quote from Paul on 07947 632976. (based in Hampshire nr Bishops Waltham)
He recently repaired/painted both rear sills on my mk1… a very good job at a sensible price, and with photo’s emailed as the work progressed, so that I could see exactly what was done.
He had to cut out rusted outer skin on both rear sills, plus a bit of floor, weld in new skin, fill, stonechip, and paint. The jack points were luckily still solid, just some surface rust along the bottom edge. PM me your email, and I’ll send you the pictures that he sent me as the work progressed. He’s now set up to do all repairs on MX5’s, bodywork and mechanical as well.
