Wheels, trailing arms, strut rods, and spring are all off. Previous owner undercoated alot underneath, but I want to spruce up the exposed frame in the wheel wells and the pumpkin crossmember, possibly the pumpkin, and the bracket securing the pumpkin. I just have some light surface rust. What do I sand with and what product do I use to paint with. Thought about Rustoleum or something like that. Possible colors? Thanks in advance for the advice.
