There was a Rolls Royce in the old storage shop with literally over an inch of bondo on the B-pillar to rear-quarter connection. Nasty stuff, but on the surface it was smooth.

The problem is when bondo dries and gets cold, it contracts at a different rate than the thin high quality steel Porsche uses, and cracks the paint adhered to both of them.

I think the old hot-rod used brazed lead melted into the seams to even them out but there are probably several options to build up slight imperfection in two surfaces to make the surfaces as one.

Paint shops in constantly hot and dry climates are probably going to give a better result due to better operator-error margin in the rust department while different coats of whatever are drying.
