It's up against the tank. My cross member has a few dimples in it as well... Metalcloak has a system that has a new cross member with it but it's double the price of an OEM replacement skid plate... and to think, I had (honestly) said I wasn't going to offroad this Jeep
I didn't realize the JK tank was there. That's probably a better place than on my TJ (behind the rear axle).
I've heard good things about metalcloak, but never used them myself. I bought my skid plates from Undercover Fab - JK Parts I'm happy with them. They are all surprisingly expensive though.
I agree, fix it as best you can. It's not like a lot of folks will be crawling under your jeep complaining the skid plate is bent ..... and you know if you replace it the new one will suffer the same fate sooner or later.
