In my infinite wisdom,I know very little about powder coating. I have frame, tank and fender that has been sand blasted and then I painted it with epoxy primer. A friend is rounding up parts to powder coat and asked if I needed anything done. Can my stuff be powder coated over the primer or does it all have to be sand blasted again? | ||

it must be clean bare metal.. aluminum should be pre heated, cast aluminum is likely to bubble "outgas" billet ( like pm wheels ) normaly wont. I would not recomend PC on pm wheels. DAMHIK | ||

I would not recommend PC on pm wheels. Any reasons? I haven't seen any black pm wheels, so I was thinking about that for my S1. | ||

Thanks Oldog. Guess I'll just paint. PC was just an option that came by......./ | ||

If you are looking for an automotive finish it might be best to blast it down to bare metal BUT you can powder coat a 2 part, catalytic cured, epoxy primer - have done it many times for a customer who insisted on ludicrous mill builds & holiday free. If the primer was applied awhile ago @ least solvent clean it. - Better yet sand & solvent clean. - Talk to whoever supplied the primer for suggestions on the solvent. | ||

I was going to have my cast V Rod 10 spoke wheels PC'd black and was told not to by my coater. They're cast aluminum. He said the exact same thing Oldog said, they'll bubble. | ||

I don't understand John. Buell wheels are Cast.... XB and Tuber. Most productions wheels are. I've seen all kinds powder coated. | ||

I dunno Dana, the guy who owns the PC company works at the VR plant in KC. Maybe the type of aluminum used? I don't know. I do know this, some of the VR's with 10 spokes have the insert (spokes) coated, but the polished rim outside isn't...maybe that has something to do with it. | ||

Yeah, I' could swear I've seen them coated. Weird!!! | ||

Tyson emailed me this........ "the stock wheels and the other bare aluminum covers on the bike, on an 06, DO NOT powder coat well at all, I tried doing mine in a silver metallic color and they came out looking like they had been fingerpainted at a retarded childrens fair. Apparantly its due to the alloy mixture used when casting them, this leaves tiny holes in the surface of the aluminium which cause bubbles to form under the coating when baking them. After a lot of hassle I ended up getting everthing painted instead and then baked and this came out looking great." | ||

I know that PM rims can be powder coated successfully. I had mine professionally polished and then done with a clear PC. They are holding up very well after 5+ years and 25k+ miles. Best part...no more needing to polish!!! | ||

Thats right Dennis. I forgot you did that. Did they even yellow at all??? | ||
| Bads1 |
Wow John thats a strange deal. Makes you wonder about chroming them then. | ||

Well I used to work for a powder coating company and we powder coated wheels all the time, XB wheels are powder coated from the factory. The real problems most people have is that in some way there is a silicone that has been applied to the metal, lubricant or cleaner that leaves a residue and that will not let the powder cure correctly. You can powder coat fender, aluminum, and if you need body work done to them there is a high temp bondo that can be applied to ensure a good surface. If they are properly treated with an acid wash most everything comes out just fine. Sandblast them first, acid wash them and straight to the paint line. The comment about outgassing is SO IMPORTANT with some materials, if you don't run them through the bake oven to out gas them it will look like $hit. If your powder coater knows what they are doing you should be fine. There are also image transfer powder coaters that can put virtually any image on the surface that is being coated and it looks like it was airbrushed. Good luck with your stuff. | ||

If your PC'r knows what they're doing you can PC cast aluminum. You need to put the metal through a heat cycle to keep the outgassing to a minimum. My PC'r had to do that with my primary cover. | ||

Dennis I am glad yours held up well,that is what led me to try it on my x1 my wheels have not held up well, the coating has cracked and is trapping water and other corosives, under it on the aluminum I live sea side that "may" have a little to do with it. the powder was chosen for use in the weather, perhaps you are easier on your bike or I am too heavy handed while tire changing, on coating cast, I had the tail of my X1 recoated its good but there were tiny imperfections, My force winder had to be stripped and re-done in black ( that was acceptable, ) all i can say is that wheels may be cast in a way that gives them a dense skin, the tail seems to be that way. PM wheels coat ok they are not cast but are billet and are not porous. They do flex more than cast and this may cause the coating to crack, I think thats why they were not coated before, I will get a wheel roller setup to wipe mine down after I strip the PC off of them stay tuned. | ||

They do flex more than cast and this may cause the coating to crack That is more of an over cure than anything else, aluminum beer bottles with a good coating on them can be smashed to all hell without the coating cracking chipping or peeling. Any cast aluminum can be coated and it can be done correctly with no imperfections if the coater takes their time and does the proper prep work. Proper pre heating as well as outgas primers are usually used with outstanding results. This is cast and smooth as glass. Best bet is to speak in depth with the coater before hand and voice what it is you want and expect.  |
