Rust treatment before oil spray?

[u/scorp171]

Got his 4R a little while back. 2010 4R limited. only had this surface rust

Being here in 🇨🇦, this looked minimal and only surface rust

want to get it treated before winter hits

I got this 2010 4Runner around a month back with just 126k miles (202K Km) here in Canada. It only had this surface rust. Confirmed no chipping of metal, and got the undercarriage tested by my mechanic as well.

I wanted to get this treated well before the winter arrives. After going through the posts, I found oil spray (Krown) seems to be the best suggested way to maintain the rust proofing over time.

However, do you guys recommend getting this corrected before the oil spray? I saw videos of people using metal wire to get rid of surface rust and using rustoleum coating. I do not plan to do any black rubber coating as I've seen it further increases the rust over time.

Recommendations?

Check out my 2010 from eastern Ontario… I scraped and rust converted it last fall. Before and after one winter:

My recommendation : clean it up first. Don’t use rubber. I wanted to see how it responded to one year without before getting it oiled. I’m glad cuz now I can re-surface the trouble areas before oil this year
