PinkSpId3r, the hardware on that J Custom will tarnish and rust. Pretty fast. Unless your body chem make up is different.
Its a gun metal finish correct?
Ibanez's cosmo/gun metal chrome/gold finishes are ... not know for lasting.
I suggest you buy a pda plastic, plaste it over your picking area. Then take it up and play. Wipe it down when done... repeat. Play it. I have my Custom guitar and I just play it... spent 3 months rubbing oil on my guitar's body. Got dinged. Got scratched. Heart ache? No. Because I realised, this guitar is going to be my guitar, my tone machine, my extention of... myself. Don't need to be hindered by anything else.
