Hi all, my Puma's MOT is due next month so I thought it was time I tackled the rust on the o/s/r arch and sill. It appears that this area has been "repaired" in the past but instead of cutting out the rot and welding new metal in, repair sections have been laid over the top held in place by copious quantities of filler. This is what I started with:
A couple of minutes with a wire brush on the angry grinder and I was left with this:
As the last image shows the rust has got perilously close to the rear beam mounting point. Does anyone have any pictures that show what the structure under the outer skin is like please? i.e if you were to cut away the bits that are missing from my car on a sound example what should be underneath? I'm very fortunate to have neighbour who's a skilled fabricator so he can make what we need but because so much has rotted away on my car we're not sure how the bottom of the arch, sill and rear beam mounting point should all be tied together.
Any pictures, drawings, links and tips most welcome!. Thanks, Jim
