Dude, your frame still has paint on it! Thats all im saying... If my frame had some paint left on it, I would be ecstatic. Last work I did rust chips were falling down like someone was pouring a box of Frosted Flakes on me. I dont think I even want to go banging on mine, if you can find holes in yours. Do whatever makes you happy, unless some very specific situation is happening here, then do yourself a favor and dont bang on it anymore, lol.

This is coming from the arch nemesis of rust. I've wheeled, grinded, sanded, and por-15'd more then a couple vehicles.
