New TTI's rusting?????

Yeah, good luck it's so tight down their your bound to get some scuff's.

I'm sure. All I can do is try to be careful.

Get a big sheet of cardboard and lay it on the ground in your garage under the headers like TTI says to do. You have moisture coming up through the slab (or gravel surface) and that is where the rust is coming from.

My car is parked on a large sheet of cardboard, but for a totally different reason.... :banghead:
