The four chromed bezels were very grubby on the outside and on the inside there was loads of rust, so I started with those. My polishing wheel brought the chrome back to more than acceptable, I then sanded down the inside to get rid of the rust, carefully masked off the shiny chrome and applied three coats of silver Hammerite. Photos below show job done.
Next were the four inner bezels that the glass units sit in and allow for adjustment of aim. This time I used a wire brush in my electric drill, clamped into my workmate and scrubbed all the rust away. Again three sprayed coats of silver Hammerite were applied.The photo shows before and after. The after is on the left, just in case there was any doubt.
The photo above shows one of the new glass bowls fitted with my first choice of a H1 LED. The final choice of H4 LED's came with their own wiring harness, meaning that the wires in the black metal buckets that I had so carefully masked off before spraying, I now had to cut off and replace with the new wiring.
And there we are; a view of a freshly sprayed bucket and the complete assembly, polished rims, new glass bowl fitted with a H4 LED already to be installed in Stella when she returns.
