I am happy with the quality and all but for the alternator cover I think that you can still buy new ones cheaper than they could re chrome them (no I have not priced the re chrome cost at M&M but they are not cheap).
HDL will sell you new for 34.37.

Besides the real problem is still that the alternator gets too hot and would bake off the new chrome in time as well.
The best fix, the one that I recommend that I have not yet indulged in, is replacing it with a nice aftermarket shiny metal cover that can take the heat.
