For those that like to argue the virtues of powder coating...
I submit this example....not a 2A but a JD riding lawn mower....(kept out of the weather in the sunny South.) Those pieces you see are pure powdercoat not sheetmetal....coming off in sheets. Just imagine this being a frame or bumper or wheel. Edited by rocnroll - 24 Mar. 2023 at 7:29pm |

If that is the virtues, I don't want to see the character defects.

Exactly. (I'm not one that argues it's virtues BTW)

I'm not a fan of powder coating paint either, but I'm pretty sure that any coating will fail if the surface isn't properly prepared beforehand and the product isn't properly applied. I think dramatic failures (like coming off in sheets) usually indicate dramatic deviation from one or both of the above.

I was afraid of using it after seeing park benches and lawn furniture after a couple years. I have read it is good for coating cast lead bullets, I need to try that sometime.

Reminds me of what I have seen when someone, not me, uses truck bed liner as undercoating, or to line the inside of a tub.
I'll stick with an effective rust preventive/converter, epoxy primer, and paint.

I will too. In my opinion this is where the PC fails.....there is none of those. It is applied over bare metal (unless things have changed over the years). |

Yup. I think most folks, amateur to professional, can paint pretty well. Powder coating seems to demand a whole 'nother level of expertise --- something akin to rocket surgery.

I’ve seen that too - blame it on moisture if you want, and I’m sure it has some effect - but I’ve seen the same thing in Eastern Colorado, in the middle of the Great American Desert. The coating seems to be thin (sometimes you can see it) on corners and edges, and that’s where it starts.

No need for any imagination. This is on my JK, something I still have problems mentioning in the same sentence with "Jeep". That fact aside, powder coat almost always SUCKS big time. Like paint, powder coat comes with a bunch of media options and proper prep is absolutely essential. It can be done right but in reality, that rarely happens and there is no way to know before purchasing something. I think I ended up with about $500 in materials rehabing that bumper by the time it was sandblasted (that didn't get all the crap out of those outside corners), reinforced/rewelded the tire carrier pivot, and rewelded almost all the seams on the back side. Probably close to 10 lbs of wire----- Then add several days of free labor with the needle scaler, sanding, skim coating, a 4 coats of epoxy primer. Someplace around 60% of it was badly pitted. Was it worth it? Probably not. Although "engineering" is in the manufactures name, their definition of that term is apparently quite different than mine. I had previously re-engineered their closing mechanism and tire carrier that was impossible to keep the rattles out of and built what has proven to be a really functional trail tool holder for it.

WHAT!!?? But I have read in many an advertisement that implies PC is the only coating method standing between you and disaster.
Is this correct? Powder coating was developed to coat lots of pieces faster with less loss of applied coating than more traditional methods. Not more effective. More economical. Electro coating is not PC, right?

Electroplating is a very different process.

Here in the frozen north I think less of it. I’m sure pre-prep is an issue as most manufacturers want profit before quality. Problem in our climate is the powder coat and the base metal have different expansion and contraction rates in the summer/winter heat cool cycles, this hairline cracks the PC and then in the winter the road salt gets in the small cracks and attacks the base metal, then the PC comes off in sheets. Our John Deere dozers at work suffered terribly from this, the boxes on the back of the cabs would rot right off the machine in a few short years, very expensive to replace as well.

I ran a sand/plastic media blasting business for 12 years. I refused to do anything that had been powdercoated after bad experiences. It cost more to remove than the item it was applied to. All the above is true.
It does work wonders with lead bullets coated. No lube needed. It will size up to a bit larger diameter and won't lead your barrel. Actually increases accuracy.

Will powder coat interfere with the bullet expanding on impact? I hunt with most of the bullets I cast and bullet expansion has always been an issue.

From target evidence after impact, I'd say no.
