While I have no idea how thick these layers might be compared to paint and primer, the chroming process does require a few layers of material.

So maybe the end result thickness is similar. Thanks!

Possibly. I would bet the difference between a chrome plated Ludalloy and a sand blasted and painted Ludalloy would be pretty minuscule. Some guys will hear a difference and some won't. Everyone's physiology and hearing range is different so one drummer may hear something another drummer may not and, as mentioned earlier, one may perceive a difference simply because they expect to hear a difference.

Honestly, I would not worry about it. Even if you can hear a discernible difference that difference will likely be gone by the time the drum is heard over the entire drum set and a band, or through a PA or recording. Truly any difference you heard between a chromed shell and a re-finished shell would probably be no more than simply comparing one Supra to another.

If I were you I would play the drum as is. If you don't like the finish it will not cost that much to get it sand blasted and reprinted in any kind of automotive finish you would like including pearlescent, metal flake, matte, semi gloss or full on clear coat. Or just have the aluminum polished. Enjoy the sound and enjoy the possibility of creating a unique instrument.

I agree tnsquint. This discussion has helped me decide to leave the drum as-is with the current paint job. Looking forward to using it at a gig tomorrow night.
