Is there a primer that sticks good w/o Alodine?

Thanks,

There's a wide range of opinions on this and never-ending debate (section of VAF especially set aside for this!)

But my opinion would be to use a 2-pack epoxy primer, after preparing the surface by cleaning and abrading with maroon scotch-brite.
The brand of primer should be based on the top-coat that you are going to use, i.e. select an entire paint "system" from one manufacturer.

Thinking about it again and how I came the the conclusion that summit was Nason, I wonder if they changed brands since your call. All the Kirker paints I have seen ( and the eastwood paints) are 3:1 mix and the gallon cans come only 3/4 full. The Summit paint was a full gallon and a 4:1 mix ratio, same as Nason. Plus the color palet is pretty much the same as the Nason branded paints.

I just started working with Kirker. Thanks Jereme. So far just the EnduroPrime, but I like it. Can't argue cost either. Super cheap compared to SW Jet Flex. Mixes easy. Wet sands in 24 hours. Seems to stick really well. I plan to use the exterior paint later.
If you want a flattened paint, call Kirker and ask about mixing a flattening agent and what rate. They answer the phone. What a concept. I called recently and was told two coats of primer, wait till fully cured. 3-5 days. Wet sand with 800. Spray final paint. Cure. Wet sand 800, 2000 then cut and buff.
