greetings

as the title says, i want to paint a rifle, was going to strip and re-blue it, but decided not to bother, the metal has some minor pitting requiring quite a bit of work, even then blueing wouldn't hide that, plus the fact that you have to jump a few hoops to get a blueing kit on line at twice the price(another story) made me change my mind

so my questions are;

1-would i have to strip it still, or can i paint over the blueing (assume that i will degrease it good)

2-what kind of black paint should i use, looking to have it close to a blued look, glossy, matte, or maybe tremclad

3-once painted, can i oil the surface

I'd be interested to know how people prep and paint their metal. I did a lousy job on some aluminum tube - the paint didn't hold well and is chipping and flaking very easily, so it will need to be stripped and re-done.

i'm leaning towards tremclad, after all, its formulated for metal surfaces

did the cutting deck of my riding mower two summers ago, painted over the factory paint after cleaning and degreasing it, came out nice, the finish is even throughout and quite durable, no pealing whatsoever, but not glossy enough for my taste, wondering if i could use a more glossy type tremclad, or maybe the same paint as i used, and then oil on top of it to make it gun metal glossy

when doing aluminum you should use etching primer so your paint will stick and last

I would try to cold blue it anyway, you've got nothing to lose.
For painting I'd use automotive paint if you can, like acrylic urethane or polyurethane, if not the best rattle can spray I've used is polyurethane meant for R/C model airplanes. It's tough stuff to resist the nitro fuel and I've used it for a variety of things needing extra tough paint.
For painting metal I sandblast with 80 Garnet or similar, clean and strip with brake cleaner, heat the moisture out of the metal, then spray my coats and bake in the oven. Pita I know, just saying what's ideal.
The bluing doesn't affect anything so paint right over it, but oils, and especially silicone will so be sure it's stripped clean. If you can't sand blast then hand sand.
No you shouldn't oil the painted surface, it doesn't need it and the less quality the paint and prep work the more likely oil will seep under the paint which will eventually pop it off. The oil would need a place to enter but that's anywhere you didn't paint such as the cocking slot, bore, or damaged places like where the scope rings dig in, screws thread in etc. Gloss black would be way too shiny imo, but semi or satin should be ok.
Another thought might be camo. I've cut out stencils with heavy paper, like grocery bags and it turns out really good. I base coated the whole thing with a medium or olive green, then added dark green, tan and black shapes.
Check out epi.com, they have both cold bluing and paints for guns. Their cold bluing is the best and cheapest I've found so far. The trick with cold blue imo is to roughen the surfaces more than you normally would. Then strip with something like brake cleaner that doesn't leave a residue, and don't touch it after cleaning. Then warm the metal to at least 100F, bluing should be warm too, and soak it for a min or several depending on the stuff you're using and its strength. Rinse with hot water and use OOOO steel wool in the direction of the sanding marks to gently clean it up. Re-blue it if needed, it may even take more dips and/or longer soak times and maybe higher temps before you're happy. Once blued to your liking apply a good penetrating oil and let it soak in, maybe a few coats over an hour to be sure it gets enough. The oil isn't just for protection, but it makes it darker too so don't judge it too harshly until it's oiled and soaked, possibly for hours. The rougher sanded finish will come out darker/blacker than a smooth one due to more metal being blued per square inch/cm. If you cold blue a smooth, or worse a polished surface it'll look more translucent purplish blue like you tried to blue it with a sharpie. The courser finish also holds more oil for better/longer rust protection, since cold blue is inferior to hot this is something to consider. I would suggest experimenting first, maybe try several small unseen sections, maybe three 1cm squares sanded with maybe 400, 180, and 80, then use a Q-tip to blue each one so you can decide for yourself how rough you want to go. Rougher surfaces also turn out more uniform which can be a problem with compete blue jobs. Once I sandblasted a gun instead of sanding, 80 grit, it ended up having a kind of matte finish like an almost black parkerized look. It was very uniform and hasn't rusted at all in 20 years.

thx Chevota

quite the process you describe, as i said, i was to re-blue it till i started looking for a complete cold blue kit, not currently available in stores in Canada, it is available on amazon.ca from american distributors, but can't be on the shelves here because the label laws changed in 2011, it now needs to be bilingual labels, birchwood casey hasn't done that to their kits yet, the price of getting on line from the US is about 2 to 3 times what you'd pay if they had it here, so with all that factored in, i opted to paint it, i'm comfortable doing that as i believe it will require a bit less metal work, and will most likely hide the metal defects a little better, really this is not an expensive European model :? .

thanks for the painting advice :)

I had my Crosman grips beadblasted though prior to powdercoating..

I used one of the textured spray paints I found in a paint store. Same thing available at Canadian Tire, I think. I went with a green/white rough stone finish (grey/white speckled would have been nice as well) - went well - and then gave that .22 Hornet to our rancher friend - after using it for a season on gophers. The rancher uses it for shooting his cows and bulls now, instead of the BRNO .22LR. He's a butcher you see.
