Can anybody recommend a paint with the durablity of POR but can be used on new/clean metal?
I used POR-15 quite succefully when I repainted the Frame of my TD. I want that same durablity on some of the replacement parts that are clean and/or new. POR-15 does not seem to adhere well to some pieces no matter how well I prep them. I've tried degreasing and soaking in Metal Prep. I've tried sanding or sand blasting. Often the fastners are zinc plated. I want long term rust resistance and I want them to match the chassie black of the car. Any sugestions?
 
Powdercoating is very durable, and Eastwood Company sells a DIY kit for around $100-150. Outside of that, epoxy primer and regular paint should work.

I think on clean new, non-rusty bare metal you'll probably want to primer it anyway before POR.

If the part is zinc plated, it already should be rust inhibitive - thats what the zinc does.
 
Guess you could hang it out side in a tree, and throw some salt water at it off and on for a few days.
 
You could also investigate Rust Bullet, another POR-like coating (I have no experience with it). Powder coat kits are also available from Harbor Freight. Better, and more, color choices are available from Eastwood. I like powder coat, but if the metal doesn't have a good tooth to anchor it, you'll find it brittle. Just keep that in mind.

If you want something that sticks well and is good with rust, drop back to Eastwood's "Rust Encapsulator" (formerly Coroless paint). That is an excellent primer for use under your regular top-coat paint systems.

Any zinc plated part will be hard to coat. The Metal Ready should have stripped it if you left it on long enough.
