powder Coating removal help

I recently sent a bunch of my parts that are chrome to get powder coated black. All the parts turned out great except for my Tank Dash Console. It bubbled up all over the place.
Ive here all kinds of different opinions on this subject. IE: you cant powder coat chrome etc., you need to chemically remove the chrome before powder coating etc,. If this is true, then why did all the other parts turn out good with just a good media blast? Is this part made of a different material. Was it poor Chroming from the Moco?
Now I need to remove the powder coating, so I can send the tank dash console to get the chrome stripped, then powder coated again.
anyone with knowledge or experience with this, your help appreciated.
thanks!

i put a lot of powder coat on my bike this winter, all parts was chromed before. Only 1 part give me some trouble, my primary cover.... the thing is, if the chrome have some defect ( you cannot see with your eye ) when the guy put the part on the furnace to bake the powder, little bubble was forming under the chrome plating and thats not turning back......I use a Richard scraper, you know the one you change the blade, the model with a very flat blade. I don't know how to say that in english.... grattoir avec lame interchangeable....it's not a big thing to do, just be patient, maibe 1 hour...

DED HD,
I powder coat so I will give you my take on this. 1) The part wasn't sandblasted prior to coating, to remove the chrome plating, 2) The part wasn't outgassed to remove all the chemicals that have seeped into the metal, 3)both 1 & 2. Both of these processes are important for good quality powder coating. If the other parts were done the same way as the dash be prepared for the powder to start flaking/chipping off.
Now you a few options. You can either send the part off to be stripped which is not a fun process for anyone cause the stripper to remove the powder isn't cheap and it is nasty stuff, then have it re-coated (I can do this for you if you want). Or you can buy another dash and have it done by a better quality powder coater.
I am not trying to sell my services by any means, I would rather you find someone local to you that does it so you can go get some face to face and make sure they are doing things correctly. If I can be of any help please let me know.

Thanks Glyddn.
They told me they did a typical media/ sand blast, and that in order to completely remove the chrome, it has to go to a professional stripper. this was not told to me until after the powder coating was completed.

Ive heard it is a big pain in the butt to remove the powder coat and that it takes a long time, and no stripper is going to want to remove the chrome until the Powder coating is removed.
Fortunately for me this was not my original dash piece, it was one I purchased additionally.
i hope the other parts dont start peeling. bubbling, flaking as this piece did. Or I just wasted time and money.

I had some parts that a friend tried to coat in a easy bake oven in his basement that went all bad that i had to strip to get re-coated. I had a can of aircraft stripper that took all of it off... You can buy it at any auto store... Oh and don't do this in the wind in front of your truck... bad things happen!

Stripping the chrome isn't a big deal, its a matter of sandblasting it. I strip all chrome pieces prior to powder coating and this is how I do it, and then I out gas them in the oven at 400deg for 1 hr. this usually takes care of any problems with the metal.
Aerosol paint stripper will work if the powder isn't adhered good, but you will still want to have it sandblasted in order to get it down to bare metal and have a good clean surface to powder.
Good luck

Its all good. I spoke with my PC. He did media blast and pre heat the parts prior to powder coating. All my parts turned out great except for the dash, in which the chrome bubbled up, not the powder coating.
He doesnt have a good enough Sand blaster to completely remove the chrome, so for an additional fee will take it to a Chrome plater he works with and has the Chrome parts dipped in acid to remove the chrome.
I also found out he has an industrial solution that can remove all the powder coating in about 5 minutes. I just didnt want to have to drive the 3 hour round trip to take it back to him.
im satisfied, and for the price I paid for all my parts, I cant complain at all.
I still have my stock chrome dash on my bike,( it was an extra one I bought that got messed up) and I may send it to get the chrome removed first, and then Powder Coated.
thanks again guys! Cant wait to get my bike put back together, with all the winter mods, and start riding. Soon! Very Soon!

sounds to me like it's a safety issue, powder coat could fly up hit you in the eye
and cause a wreck.

YOu are hereby man-authorized to purchase a new Yaffe Tank Console please inform

We suggest you order first, take delivery and then after installation if questioned casually say "oh that, been there for months, surprised you hadn't noticed, btw did you get your hair cut it looks fantastic"
