Just picked up a used Polaris RZR that had more frame rust than I expected. Thankfully, the rust appears to be on the surface and there is little degradation of structural integrity.
I’m looking for something easy to use with not a lot of prep work. I’m not very concerned about how it looks because the unpainted components aren’t really visible.
I was thinking about coating the rust spots with a rust converter, followed by an encapsulating product, and then finally painting over everything–or maybe bed liner or something durable. Any tips, product recommendations?
Prepping the rusted surface is critical to whether or not an encapsulating coating will adhere. If there is extensive pitting, then the rust converter won’t work. If the rust is merely surface rust, then a good quality rust converter can be applied to seal the pores in the metal. Following that treatment, an encapsulating coating should adhere well; but it will have to be overcoated with some kind of paint or finish such as bed liner. It also prevents re-rusting of bare metal effectively for two years in all climates.
After using Rust Bullet you should prime it before sealing it with another product such as E-Coat or Rust Encapsulator (if you want it to look nice). You can do this by spraying on our Seam Sealer or any primer that works with the topcoat.
You can also use Jax Wax SteelWax, but I would recommend brushing it on and wiping off the excess before applying the next product since there are some rust conversion chemicals in it as well. The brushwork will help knock down any re-growth of rust at the edges of the affected area.
Boeshield T-9 will also protect against future rusting for a couple years and is solvent based so paint thinner works great in cleaning up afterwards.
