I stopped by my brother in-laws powder coating shop today to have some parts redone because of some scratches. I throw them in the blast cabinet to see if they were powder or paint. If you know anything about powder coat then you know that powder coat should not blast off. You have to use a chemical dip to remove it, at least if it is done correctly. The rear brake pedal stripped in the blast cabinet fairly easy but it was powder. The top triple blasted off very easily and was paint. The problem I have is they never prepped either part. Paint comes off quickly but you can see the layers as it comes off and there was a shiny layer under the paint. There was little to no prep done to the part before it was painted which explains why it was starting to chip. The brake pedal was just awful. Like I said, powder should not blast off. There was boot wear on it and I can see why. If you're experiencing any chipping of painted parts or wear on the powder coated parts it is because Victory cheaped out and didn't prep the parts correctly. I had my brother in-law powder coat parts for me 7 years ago and they still look brand new. I've helped him out in the past when he was really busy and once in a while he'd get parts back that he already powder coated because the customer wanted a different color. I tried blasting them and all it did was take the shine off the part, the powder wouldn't budge. If you plan on having any parts redone, check into the shop you're sending them to. If they don't do the proper prep you'll end up with the same problem all over again.

You put any powder coating or painted part into a blast both with a 120 psi paint will come off
sand blasting or media blasting will take off any powder coating
I think you're all wrong.

I agree with VJ... I have had old powder coated parts that I had sand blasted. These parts where 5+ years old and they looked new and was still able to blast them.

If the part is prepped correctly, it shouldn't come off unless you blast on it for a long time. This was coming off fairly easy. Don't get me wrong, it was stronger than paint, but it was definitely not good powder coat.
There was a time a few years ago when another shop opened up close to where my brother in-laws shop is. The new shop was cheaper so he lost a lot of business, for a couple months. People figured out why the new guy was cheaper. He didn't do any prep. My brother in-law got a ton of the other guys parts because the powder was chipping off. Throw the parts in the blast cabinet and it came off the same way my Victory parts did today.
So, if you're going to say I'm wrong, what's your experience with powder coat? I have no problem admitting when I'm wrong, but when I've had experience with something and know I'm right, you're going to need some serious proof.
FYI, Ness chrome is some of the worst on the market, it peels off like tin foil. It's as bad as HD chrome parts from the '80s. Good chrome in the blast cabinet fogs over but doesn't peel, Ness chrome comes off as easy as paint.

Next time I go to his shop I'll blast on one of his sample parts and take a picture of it. I promise the shine will be gone but the powder will still be there.

Why can't we all just get along?

So a superior prep makes for a superior job. Agreed?

So put a PC part in a cabinet and an experienced eye will be able to tell how good a job it was by how it reacts to the blast. Agreed?

It is likely that in a mass manufacturing environment Victory does not always prep coated and painted parts to the degree that owners would like to think they should. Agreed?

OK folks, move along. Nothing to see here.

Hmm...ive media blasted parts, done some at home powder coating and watched hundreds of 'how its made' shows and I have never seen or read of any powder coat prep outside of degreasing.

That might be the issue here. I am used to him doing all of my powder coating. Even when I buy new parts I opt for polished if I can and have him powder coat them to the color I want because I don't trust half the crap they put out there. If everyone else is used to buying parts already coated and don't know that it could be better they think that is just the way it is.
Powder and paint are the same when it comes to surface prep. A scuffed surface allows for a better grip, longer life and better finished product.

Who's to say the parts are not painted and you just believe its power coating


After sandblasting you'll want to clean the dust off but there will be no need to sand

I was under the impression powdercoating only required a (media blasted) clean, degreased surface...never had anyone suggest I scuff it first.
The blasting "scuffs" the metal. Usually use a semi aggressive media like aluminum oxide to get a slight texture to the metal. Blasting with things like soda aren't aggressive enough to get a good etch into the metal.

No way was this paint. Like I said, it was stronger than paint but definitely not as good as powder should be. If I didn't already blast it clean I could have thrown it into the chemical dip to prove it but it's too late now. The chemical dip will strip powder but doesn't do much to pain. Just like how aircraft stripper will take paint off but won't do much to powder coat.

hand done work beats mass production...wow somebody call CNN with this breaking news lol


In all seriousness everything from the prep to the material suppliers can impact the finished quality and an informal media blasting test isn't exactly a way to make a final judgement. If your talking about a level of effort difference at 120psi vs one not changing at all it's a big gap.

Not sure about any of you but I plan to avoid and dust storms here in AZ that are whipping my bike at 120psi.
