I got several aluminium extrusions i would like to paint in white, RAL 9010 and with a grit finish like pic rel. Question is, how do i do that? Preferably without shooting a hole in my wallet.>Is this doable with off the shelf can products?>What am i most likely even looking for? There seem to be quite some options; lacquer, powder coating, nano coating, etc..>Is there any kind of standardisation regarding amount of grittiness?>If all fails, can this be done in a car shop or do I need to find someone more specialised?Whole thing should be somewhat heat resisent as well as i it's standing under an oval glass ceiling.Yes, i tried to look this up. However these days Google is apparently only ever smart enough to show you cans without any indication what the end result may look like, posing carfags, and shops selling to aforementioned car fags. Neither of the last two giving any indication how anything is actually done. And don't get me started on getting anything out of Chatgpt regarding what these kinds of coatings are actually good for.Color is probably the easy part, but else i'm trying this whole thing with good ol no experience.
>>2888305truck bed liner + color coat?also they make stuff like this, I used it a long time ago on an art project and it does result in a gritty, sandy-feeling surface.
>>2888305Those are “parkerized” However what we used to do with Hondas back in the day with our aluminum covers was to use a “crinkle red” spray paint to make our non-type R civics look like they had type R motors
>>2888334>truck bed linerThanks, anon! That looks pretty much like what i had in mind.Unfortunately not a truckfag, so the thought never crossed me.
>>2888305Shot peen paint.
>>2888388If you want it to last you're gonna need to prep and etch prime the metal.
>>2888305Go to a hardware store and just look at the paint section, you should find the right kind of thing. I've used it before and gotten pretty good results, it's pretty obvious from the cap of the spray can but I can't remember what it's called.
>>2888369>sieg not being stupid challenge: IMPOSSIBLEYou can't put a phosphate coating on aluminum. It only works on ferrous metals. Moreover, that's not at all what a phosphate finish looks like. Like it's not even close; parkerized iron is a distinct dark grey/black. OP's pic just a stone effect/textured coating.Off-the-shelf options are available. Or you can do similar pretty easily with most spray guns: Adjust the gun so it sprays spatter instead of mist and do several coats of similar-ish colors, letting them dry completely between coats.
