Rust prevention questions

[plym49]

OK, I did some Googling and I found the name of the products and the vendor.

The vendor is commanderchassis.com. They are a fabrication shop and they also sell fabrication equipment. Additionally, they sell these two liquid products.

SP3 is the Gibbs alternative. I found it to be pretty good. I did not do a head-to-head with Gibbs as I never really was a Gibbs-freak (not that there is anything wrong with that).

Fluid Film is the rust preventive spray. Also available in bulk, and apparently Graingers sells it.

I would definitely recommend Fluid Film for anything that you want to keep from rusting (in situations where a thick, sometimes sticky build-up is not a problem, like for items in storage, engine compartments, the undersides of vehicles, and like that.

Fluid Film will accomplish everything that the OP wanted to achieve without stripping, touching up or repainting anything, and a few bucks for a spray can is way cheaper than bed liner.

Painted surfaces do not rust. If it's got a good coat of paint on it, you should be good to go.
Touch up any scrapes / scratches every summer.
Or throw money at covering it with something else and touch that up every summer.

as already said POR15 will not stick to anything but bare metal.

In my experience in mil spec packaging, Volatile Corrosion Inhibitors (VCIs) (sometimes referred to as vapor corrosion inhibitors) provide excellent protection for metal surfaces and can prevent corrosion for many years. VCIs are chemicals used directly on the product that needs to be protected. They are designed to create an invisible barrier, keeping moisture at bay. VCI molecules attach themselves to metal surfaces to form an invisible, thin film only a few molecules thick.

You might want to check out Durabak.
It's very tough stuff you can roll, brush or spray on. (It's a polyurethane coating)
Requires minimal prep.
I haven't used it yet but I'm going to paint the bed of my deuce with it.
