190SL Rear Wing / Quarter Panel Frame Filler Panel Repair
Whilst the body was upright on its side I had easy access to the lower portion of the rear wing forward of the stone guard. It appeared that the 190SL had been jacked up at this point causing damage to the lower lip and filler panel joining this lip on rear wing / quarter panel to frame. Rather than panel beating or fabricating a repair panel this was filled with bondo / filler. Looked perfect with paint but a magnet indicated filler and drew my attention to stripping down to bare metal.
The damaged body panel and frame filler panel were cut out. This provided access to the inner portion of the rear wing, which was remarkably rust free. This was acid washed, rinsed and sealed with epoxy primer.
The remaining lip and panel was panel beated to ensure that the curvature followed the contour of the body. It was important to get this part correct as the rocker sill chrome, door and stone guard will show any bad contours. A cardboard template was transferred onto a flat piece of sheet metal. The curvature was made with a hammer and dolly and the lip of the covering panel fabricated on the edge of the work bench. Both panels fabricated were welded in after an initial trial fit. This area was finished with lead solder.
The rear panel after metal work and lead loading produced a nice base for paint. The chrome eyebrow moulding holes were checked for correst location and contour with the body. The chrome moldings need work on the edges to perfect a fit as the contours did not follow that of the eyebrow sheet metal. Possibly the reason for this was that I was trying to fit new replacement parts to original factory rear panels. The tooling over the years may have worn or these have been re-manufactured to fit the new factory panels. In fact a few 190SL's viewed with new panels and chrome moldings showed that these did not exactly fit like a glove. Another reason to pre-fit every part to the body before final paint. I like to pre-fit when body is in metal and after the primer stages before top coats are applied. Time consuming, but you can appreciate why a professional restoration shop's labour hours can accelerate quickly. 
As a matter of course all chrome work was trial fitted to the body during metal work as well as during the primer stage to ensure correct fit. Any cutting or adding of metal to perfect a fit can be done at this stage.
