Purchased my tundra from a private party 2 yrs ago who had the frame treated with their rust inhibitor spray in the spring of 2014. At that time he complained the service was unsatisfactory and requested a replacement but was denied. Fast forward to today I'm stuck with a hole the size of my fist near the transmission cross member and nothing Toyota can do about it. I've been in the automotive industry since 1985 and know that spraying anything rusted only traps the rust inside and continues to deteriorate. Maybe this is why Toyota only has a one year warranty on the treatment.
