frame powder coat removel

[brandname]

Hi,

so recently i decided to spray over the top of my powder coated frame to tart it up a bit and everything was going fine untill i added the laquer. This has obviously created some kind of reaction because it has changed color :(

So my question is

Does anyone know what the best method is to sort out my frame. I have phoned up about sand blasting but was told that because of the nature of the powder coat, sand blasting could pull of chunks of aluminium.
He suggested acid to remove it but at a cost of about £60-£100.

Does anyone have any suggestions on this?

thx in advance. :bang:

you can try aircraft paint stripper. you can find it at auto parts stores, and comes in a blue spray can. this stuff is awesome, and will strip off about anything

not sure what it'll do to remove powder coat, though.

maybe a soda blaster? media blaster?

I googled it and found this: http://www.pfonline.com/articles/clinics/0500cl_pwd1.html

if the paint is in good shape but just bleeding thru you could try a primer sealer

The only way that I know of to remove powdercoat is to sand blast it. Most powdercoated frames are steal or chrome molly. Aluminum frames are usually just clear anodized.

Sand blasting is what i was going to do, untill i phoned someone up about it and they said it can remove chunks of aluminium. Im assuming its an aluminium frame, Its an 01 rm 250.

Basicaly i primed over the top of the yellow powder coat and then sprayed it a nice silver but then when i put on the clear laquer it then turned grey, Much like the color of the primer.

This is why i have decided to take it back to the bare metal but i never realised removing powder coating would be so difficult.

Ummm no the only aluminum frame in Y01 was Honda. You should be fine getting it abrasive blasted, I'd suggest a place with a little knowledge on lighter material and not the place that thinks powder coating pulls chunks of aluminum with it. The subframe is aluminum but that just unbolts from the main.

why try to even take the powder coating off? just remove the spray paint you put on with a paint stripper, then respray it. it sounds to me like it was your paint and clear coat that reacted, not so much the powdercoating underneath

I second that emotion.

i ended up just keeping it the color it turned out, doesnt look too bad (gun metal grey), I would post a picture of how it looks so far. I have just fitted the swing arm and front sus but the file size for photos is pretty limited here :(

Im just hoping that the laquer is up to the job of stopping the spray paint getting scratched and revealing the yellow powder coat underneath :yikes:

Post the photos to a picture hosting site then link to it if you need a larger format for your pics.

Laquer is no where near as durable as enamel, expect to see your yellow powder coating in short order.

yeah i thought that might be the case, Anybody got any ideas how to keep the new coat on? Is it going to have to be a case of laquering it to death?







These photos are off my phone, hopefully one day i will take one thats in focus :bang:

when we paint something on my car we use eastwood extreme chassis black. the stuff is incredibly tough. unfortunately i dont know how it would work over the lacquer. it is recommended to use over a primer (eastwood sells a specialized one) which is recommened to use over bare metal.

If you have it that far apart still just take it all the way down, get it stripped and then recoat it however you choose (paint, bedliner, powder coat...)

Aircraft stripper will remove the powder (If you follow the directions exactly), as will media blasting (I don't recall what media I used). This is not a fun task though; long, tedious, and messy.

The pictures you see are me begining to rebuild it, I had the swing arm off to change all the linkage/swingarm bearings and thought i would tidy up the frame aswell.

I would just like to get something done with it because its got to the stage now where winter is over and i need back out on my bike. :pissed:

I might try that aircrat stripper, Was really wanting to have it back together by the weekend though :ugg:
