Would like to clean and coat the surface rust from under the C10.
What have y'all used and liked?
Thanks

I used chasis saver on a blasted frame. Truck hasn't been on the road since, but it's on there like a rock, smash it with a hammer, dig into with a wrench, it doesn't come off. Think I still have some on my skin from 3 months ago. So far very happy-just my uninformed opinion...

I used this stuff.
Sprays on nice and uniform, rubberized too.

It all depends on your surface prep. Good paint over so-so prep is worse than bare. The coating locks tightly together and moisture gets underneath and rust forms. My $.02

I soaked all the front end components in a molasses water 1:9 mixture in a 44 gallon trash can.
They came out as bare metal. Rinsed off with water, let dry and sprayed them with a couple of coats.
Some parts that were really coated with gunk took longer than others.

I got to try this molasses trick. Can you keep the mixture around for a while or does it go moldy?

You can keep it, it doesn't lose it strength.
Keep it covered though with the trash can lid.
B/C after you use for a while it smells like dirty gym socks.
Oh, and don't leave any parts longer than needed to clean them, B/C it will continue to eat the softer elements of ferrous metal, and softer things like sheet metal. Ask me how I know...

I have used POR15 and Chassis Saver with good results for frames.
When it comes to underbody, on the outside I have primer sealed them and used rubber coating or raptor liner type spray on material.
