REALLY stubborn powder removal

[BClapp]

I have spent about 9 hours trying to sandblast a BMX frame. It has a layer of paint, a layer of primer, and then on the bottom, a layer of powder coat. The paint and primer came off with no problem, but the powder is being miserable. I have tried powder coat removers, super high strength paint strippers, almost everything i can think of. I am thinking about putting a grinder to it with a sanding wheel, but seeing it is all 1 1/4" tubing, I am afraid of the grinder marks being noticable. Any ideas or suggestions?

put it in the oven for a cure cycle. if it doesnt bubble up, you should be good to coat over it I would think. If it does bubble up, then you have your removal aid!

Thanks! Here's another question, the frame is dark red, and its going to be a kawasaki green color, any chance that could show through?

If your sure it's powder coat on it, just coat over it. Spray the new powder on and look it over closely w/ a good LED flashlight before it goes in the oven.Touch up any light spots you see. If you cant see red before cure I wouldn't think you would be seeing red after.

I have heard of some reds bleeding through before. I have never had it happen personally, but I have heard of it. The only time I have heard of it is when someone has applied a new red color and tried another color over that, I do not know if an older more cured coat would bleed or not.

If you still need to remove whatever the base coat is, consider a commercial blaster. These guys do this for a living and should be able to get it to bare metal in about 15 minutes.

Sometimes, it worth the time/money/effort saved to farm out such work.

I blasted most of it, thought I had all of it. The little tiny pieces of red bled through ..... lesson learned

It was the job that would never end, but its done now, and I don't ever want to see it again.... It was worth a try covering the red, just didn't work out. No hard feelings ATL
