Spray painting stainless steel

[TFin04]

I'd like to paint my 700 5R that has a stainless barrel and action. I did a test run on one of my muzzleloaders which also has a stainless barrel and the Krylon flakes off the barrel without much effort. I have painted a number of parkerized and anodized rifles/parts over the years and it holds up pretty well.

Is there a primer or base coat I can use on stainless to make it hold the Krylon better? A google search revealed self etching primer, but I don't know much about that product and whether or not it's suitable for my needs.

Any tips? Thanks guys.

Did you clean all the oils off and use a primer?

Paint needs a surface to grip onto... Parkerized surfaces are full of craters that hold oil extremely well.... If you park steel and dont touch it, it is a great surface to paint.

Most stainless guns are polished and the paint does not have anything to grip onto.... I would do a test run with a de-greaser and then blasting with Aluminum Oxide to prep the surface. You can also bake the surface at 350 to verify that no oil is left behind the process....

Watch a few videos on you tube from Brownells on prep for their finishes or the videos for prep by Ceracote or Durakote.

Self etching paint.

Remington SS barrels are blasted and more than rough enough to take paint! you shouldn't need a primer. If its flaking you're either not prepping it right or not letting it cure long enough. Scrub it down with acetone and handle it with clean latex gloves so you don't contaminate it with oils on your skin. I also find that krylon can take a while to fully cure, in humid places as much as a couple weeks. Until it's fully cured it's much more likely to come off. Once it cures and it's on a properly prepped surface it should only come off with wear or chemicals.

Yes the other barrel was prepped (it is blasted as well, very similar appearance to the 5R), but it may not have had time to cure. I have painted and shot AR-15's within a few hours in the past, maybe I need to just let these sit longer. I'll try a primer on the 5R and see if that helps as well.

Thanks for the info.

In case anyone runs across this post down the road, a self etching primer did the trick perfectly. I paid almost $11 for a can of it at the auto parts store, then saw it on the shelf at Home Depot for less than $5. I used two light coats of primer and the Krylon stuck perfectly.
