Topic: Powder coating

[grcamna2]

great weather this weekend...  Yeah,I'll enjoy that !

[Hon3ybadger]

I do not intend on stirring the pot but I dropped my surface rusted frame and extras off to Portland powder coating this last week. I asked why they prefer to blast and cook frames compared to dipping them in etching chemicals. They said it's because the tubular frame can fill with the chemical and never drain out. Or worse than that, leak out during powder coating or baking and ruin the finish. They said the ovens only go to 400F. I removed the vin plate on the neck because the guy said it would not survive the oven. Prep and single coat- $225 add a second coat $325

What is the best oil to use in a bike that has a powder coated frame??

Possibly baby oil on the right hand....

Damn it I'm left handed

MarkCB - Thanks for the lesson in metallurgy! Now, i can skip going back to university to get my degree. The things we can learn on this forum!

I don't think anyone can dispute your points technically. If I may be so bold, I think the point Powderman might have been making was it wasn't necessary to heat to that level of temperature for high quality powder coat on a motorcycle. There's no disputing in an industrial/commercial application it is needed, but not for motorcycles. Does it harm the frame? Apparently not per your technical documentation. Just not "needed" for these parts.

There's no doubt your contractor knows his business very well, as Powderman knows his very well too. Just different ends of the service spectrum perhaps is the bulk of the misunderstanding.

Enjoy some great weather this weekend (finally)!

Indeed!

Commercial/production coating is a completely different animal where the process is a combination of prepping processes that will result in an "acceptable" finish for the , as you say, narrow margin of profit. This can only be done by cutting corners that would be unacceptable for custom work. You won't find many places like that that will media blast the parts for the best adhesion and longest lasting durability. Seldom do these places do work for the end user. And the finish is not usually the show quality that a reputable custom coater can put out.
The heating before cleaning process is called outgassing or burn off cycle. Outgassing is done to cast parts that during the cooling process out of the molds casting debris and gasses get trapped in the pores as they close. When these parts go in the oven to cure these pores open and wreak havoc on the powder surface by creating bubbles and trash in the finish. These parts go in the oven at 450-475*F for an hour so these pores open and purge all this crap and then after it cools the blasting process take place ridding the part of this debris. The higher temps are to ensure that the pores that will open at cure temp will have already opened and purged. Old oily parts whether cast or not are put through this same process to bring to the surface these oils and greases and bake them off and bring them to the surface to be blasted off.
There are literally an endless amount of colors and textures that can be had. One of my suppliers has over 7500 colors in the archives and any color can be made, as well as many textures from wrinkles, crinkles,fine textures, heavy textures. Metallics in many colors. I can 99% match just about any car color on the market.
Properly cured powder is not effected by any oil.

^^ What he said... Also anyone interested in seeing some color options can go to http://www.prismaticpowders.com/ the possibilities are endless.

Ultimately, I wouldn't bother doing small parts if I can't do my own frame. And an oven isn't realistically viable for me. I did call around but haven't found anything for less than $300. In the meantime, I'm stripping the frame, polishing the engine, and continuing my search. Thanks guys.

One bit of knowledge that I didn't even think of that one guy told me was, that I needed to remove the bearings from the frame in order to powder coat. I guess taping things off isn't realistic.

Having read all the replies, I have come to the conclusion that I'm getting boned on the price, the thingamajig heated too much may or may not cause an owey on my whatsis, and I don't need to keep spitting on my hand. Thanks again.

I'm trying to find you someone in Boston that will give you a fair price. What exactly do you need coated and what color do you want it. Year/Make/Model, frame, swing arm, etc.?

Kind of the problem with most things here, guys post too much BS and it becomes impossible for someone without experience to base a decision on, only thing that can happen is the advice seeker will gain experience as they try random samples of the expert advice they receive.

Like we all have learned though, you get what you pay for, and you pay for experience.


I like to enter these little debates, the thin skinned bail or call names, doesn't matter, only one can hurt you on the internet is the identity thieves.

It's all Good. I have become pretty good at making two of these old machines hum along partialy from reading and interacting here.

If you can't find an affordable option for power coating locally, then try POR-15 chasis paint. Many members use it and swear by it's results. Some even spray clear coat over afterwards. It is possibly as close to a durable finish as powder coat, for a lot less money.

I love powder coating, and use it everywhere I can, but I understand not all projects have the budget for it.

I really appreciate it Powderman. I just got the latest quote… $675 to prep and coat, + $150-$200 for 'special colors". Good Lord. I only paid $300 for the bike.

All I'm looking to powder coat is the frame and swing arm. Though in retrospect, if it's going to cost an arm and a leg, I might as well add the trees and kickstand.

I always enter this site with an open mind and a sense of humor. I'm not a technician or even really a mechanic in any sense of the terms. I do like to know what my options are and use them to make decisions based on what is best for me and my situation. In this forum, you've got to take the good with the bad and go from there.

This is in reference to a 1977 cb750k. Depending on cost, I would like to have the frame, swing arm, trees, and kick (can't think of anything else) done in gloss black. I really appreciate your help. Thanks.

You must have "sucker" tattooed on your forehead to be getting those kinds of quotes. What was the $675 quote for? What special colors were you wanting that would have added that much to the job? Explain exactly what you want done and I'll tell you what I would charge. What place gave you that quote? Did the quote include Vaseline or KY?

I'd be just under $400 for that. Special color would run at most $35 to get a pound of any color in stock and that would do more than what you have to do.

[calj737]

Man, for $675 it should include KY, popcorn, a pack of Teojans, AND the Morning After Pill! Geez, I don't think I even paid that much for my entire last bike (frame, swing arm, 2 hubs, side covers, sprocket carrier and an exhaust).

I think that tattoo says "Rape me PLEASE!"...

lol I know a guy who did the entire floor pan of a vw in semi-gloss black powder. I doubt he charged much more. Just sayin. Thats a lot of surface area. The por15 stuff is amazing. Everything they sell seems to work really well. On another note, my buddy did his kawasaki 125 frame with Duplicolor Grabber Green engine paint. It matched his plastics almost perfectly and held up pretty well. He did many very thin coats and then let it dry for about 10 days.

[Vinhead1957]

I had a guy in Bradford Ma do my frame for $125.   I stripped it myself.   

[Powderman]

FYI, if you take it to a "for real" powder shop you are wasting your time stripping anything yourself. The price the quote you should include everything from stripping , blasting, coating and the cost of the powder. I don't care how much work you put in it blasting/stripping it, I am going to blast it anyways.

[thelowmax]

For the record, all I've done is Google "powder coat Boston", go through the list and call, leave a message (not one has picked up the phone) telling them what I'm looking to have done, and they call back with a quote. Out of 9 places, only 4 have actually called me back. They couldn't see the "sucker" sign anyway.

All I want done is my frame, swing arm and trees, in gloss black.

When I had two frames powder coated they sandblasted the almost clean frame.
Then they dipped the frame in a phosphoric acid bath to stop all of the corrosion inside the frame. Then a rinse tank.
After powder coating the frame was heated to 350º for a number of hours.

It comes out looking like black glass and very tough and resistant to scratching and nicks.
Worth every penny.

You don't want to over cure the powder by leaving it in too long or it becomes brittle. The part is suppose to reach cure temp and stay there for 10 minutes, not a "number of hours"

What is the best oil to use in a bike that has a powder coated frame??

Oh nicely played sir, nicely played!
