Rust "Proofing" The Tacoma

I started using CRC after RP–342 changed the spray nozzle. CRC is definitely thinner but much easier to apply. This is a 2019 Jeep Cherokee I coated last year. Still looks good.

Does it “creep?”

Like Krown, I need something thin so it will creep into my already rusty rocker panels.
Yes it creeps in warm weather. Mostly solid surface in the cold. I like that because I don’t want the winter sand and salt sticking to the undercarriage. The 2nd pic is over the winter. As you can see, I missed a spot on the subframe weld and rust is bleeding through. Warm now so it’s creeping. Pic of that spot today. It’s covered over. I didn’t have to do anything.

This is not a solution for rotted rocker panels. This is something you use on a new or almost new vehicle to keep it that way. Some surface rust is OK as you can see in my pictures.
