Due to repeated vandalism one of my clients had a sign blank cut from stainless steel and had the hardware welded on. My question is what type primer should I use on this? And after I prime, will 'one shot' be okay to use? Thanks for any tips.

from my experiance stianless..dont like to be painted. sorta like buildin a barb wire fence ..with a gate. dont understand the need for stainless. .060-.080 painted alum would work as well and you can paint on it.

When things like this happen to me ,I visit my buddy at the autobody shop. They have a lot of knowledge on painting bare metal. Maybe you could have a local bodyshop give it a primer coat for you.

the first thing is "etch the surface" before painting. (scuff it up.) in other words make sure the surface has "tooth" to accept a primer.
go to your helpful paint store and ask about primers for stainless steel.

Clean the stainless with something like Rapid Prep,or if you don't have access to that use plain soap and water,don't use denatured alcohol or commercial wax n grease removers,scuff it up and use a 2-part epoxy primer,after that you can topcoat the primer with anything you want or would normally use.

.....If the customer INSISTS in the stainless, ditto's on the scuffing AND on the body shop info.............find a really good auto paint store an' do it yourself if you have a compressor an' all. Ditto's also on the .080 aluminum with the baked finish...I have excellent success usin' it and scuffing an' finishin' with an automotive enamel finish. Have fun, sweets!!

They build Firetrucks out of Stainless Steel, and have been doing it successfully for over 30 years. My suggestion is to contact one of the local Automotive paint suppliers. I am confident they have something that will work.
You need an "Etching" type Primer. PPG, Dupont, and Sikkens all make one that works on stainless
I too reccomend scuffing the surface to give it tooth prior to putting the Etching primer on it. try one of those scotchbrite pads.
