Played rear mudguards today. Dirt Cheapo fleabay purchase with big ugly dab of bondo (which probably put a lot of people off ) required investigation.
No surprises, nicely powder coated with rust underneath, bondo softened with a heat gun, off it came in chunks. Lace curtains underneath, as expected. Couldn't be arsed to fire up the plasma cutter, so Angle Grinder with a nice thin disc to cut back to sound metal, and a quick spray with rattle can paint to prevent further rot while I plan the best way to proceed.
No sweat, easy peasey.
Swarfy.
