Awesome, thanks for the advice. I think I will try the rust-oleum rust reformer/nox rust combo for the areas I see for now. It will be something I need to pay attention to every year.

Hello, I'm new to this forum and just recently purchased a 15 Sierra 1500. I understand GM's frame wax coating and I have a few visible rust spots where it has peeled off and needs to be touched up. I purchased a can of the Nox-Rust X-121B and plan to wire brush these spots first then apply rust reformer and finally the nox rust. Would I be ok doing this? I do plan to one day have the wax removed entirely from the frame and do POR-15. Also does anyone recommend getting rear frame plugs to cover the holes? Would that help in preventing rust forming in the tubes? Thanks!
