So my Trailblazer's frame/undercarriage is pretty rusted so this upcoming summer I'm planning on trying to fix it up before this issue gets any worse. I bought some good wire wheels to grind off most of the rust, rust reformer to seal it up, rubberized undercoating spray to seal it up even more, and lastly some RP 342 to top it off. Does this seem like a good plan? I'm seriously asking cause I don't want to grind and spray all this stuff just to have it peel off and ruin the frame even more. Does anyone have any tips about this stuff or know which way is best to do this? Any advice will be very much appreciated.

Any thoughts about welding on some reinforcement steel?
  1. I have given that some thought but the frame is still in pretty good condition (no holes or major thinning seen so far) so I don't see a big need in doing that. But if I see any bad parts I will weld on some plates. Thanks for the reply
