Fuse Comes Apart

I  have been taking each piece out one by one and deburring/dimpling etc as I go.  This hopefully will help me keep them in order and ensure I don't miss anything as I go.  Next steps after the fuse is torn apart is to determine amount of interior top coat I am going to put on now.  This is a big dilemma and would be an easier question if it weren't the middle of winter where top coating in my garage might not be the best option.  I will keep doing the research and we'll see what ends up happing.   For now though, it is continuing disassembly, and then onto the metal prep.
