I remember a magnet being essential when buying a used BMC or Ford in those days. It was the best way to spot sprayed over filler.....
This is looking about as structurally intact as a real one....The area around the top of the headlights was always bad I seem to remember....
Why else did we buy newspapers in the seventies if not to use in filling holes in our four door racers. I took the wing off my Fiesta once (which incidentally had a foot spa in the passenger well when it rained LOL) and the garage said they couldn't fit a new one as there was nothing to weld it too other than filler and newspaper!!
When I sold my first mini to a mate for scrap he simply ripped the rear subframe out as most of the mounting points had turned to weetabix. I have fond memories of bombing up and down the country in it, but in reality it was a death trap!
I too had the foot spa in one of my minis - drove back from a show in pouring rain with my feet in 3inch of water
My mini 30 anniversary special had plenty of filler from new - there was a bit of rust bubbling on the door. When I investigated I found half an inch of factory filler across a large portion of the door. Someone at the factory must have bashed the skin in and rather than replace they just filled it. Lovely job though - couldn’t tell it was filler until it started falling off!
My last classic mini was a brand new 1998 sports pack cooper with delivery miles - I found that they hadn't even bothered to spray the underside / inside of the wings and front panel so the front end was dissolving
Anyway, back to the build - don't have a lot of time on an evening so needed something quick to do
