I got the "towing package" on my '98 K1500.
It's rusting out *really*
badly along all the welds.
A few more points for GM quality, I guess.
Anyhow.... what I'm thinking is wire brush the areas thoroughly
and paint on a couple coats of rust converter.
Any ins and outs to this? I'm thinking maybe something to deal
with propagation of rust into the welds where cracks form.
