Restoring old NTCs to make a coffee table

[Kenny_Z]

Just like the title says, I'm looking for a way to restore a couple of old NCTs to possibly turn into a coffee table like this:



The tires aren't in bad shape. One has low tread in the center but I could make that the bottom tire. I've got tons of aluminum around and I might even be able to score some stainless to really make it an interesting piece.




I'm going to wash and scrub them with Dawn. I'd like to put something on them to shine them up a little but I have idiotic pets that might lick these things. I don't want something toxic on the tires that might poison them. Any ideas?
