I am working on a restoration of a 1962 Chevy, and I just acquired the correct Frigidaire A6 air conditioning compressor. I know that I will need to reseal this compressor, so I would like to get it cleaned of all paint and small rust spots before I take it apart. For this reason, I believe that the best method would be to blast it, however, I am not certain exactly what to use. There is a stamped steel data plate that I must preserve all the detail on it, so I was thinking of using black walnut shells. A friend suggested that I use glass beads instead. What are your thoughts?
I will be removing the clutch and pulley first, and taping up the front collar, and adding a block off plate to the rear where the lines come off, to keep the media from getting inside. I will then repaint it, and disassemble, and reseal it. I want to get it opened and resealed as fast as possible, to minimalize the risk of contamination to the inner works. The other reason for painting before I disassemble, is that when it is being reassembled, I will need to add a lot of oil to the seals and the inside of the case to minimize the effect of friction to the large rubber O rings that create the front and rear housing plates.
