Anyone use “Rust Check” instead of Krown for rustproofing their Tacoma?

Hello all, I’m finally biting the bullet and getting my Tacoma “rust proofed” after trying to keep the undercarriage clean and patch up rust as it started. Trucks only a year old with lots of mileage but still basically rust free and it’s too time consuming to do anymore. I know a lot of guys here love “Krown” grease spray for under the truck and in all the cavities but has anyone ever used “Rust Check”?? It’s also a Canadian company, good reviews, similar to Krown and has an applicator in my closest city who is very well reviewed. He’ll go over the entire truck, find any tiny rust spots (there’s not many) sand, rust inhibitor, apply primer and frame paint, then spray the truck with this mineral oil everywhere. So, anyone use this “Rust Check” brand instead of Krown and have things to say about it? Thanks!
