Damn I really hate this stuff!
I need to remove quite a bit of powercoat from some metalwork but have yet to find a good method. Any advice/tips/tricks gratefully accepted ;D
I have tried most things in my armoury but with zero luck. Where water has got in under the surface, I can pull off big flakes of it but where its not been affected by water it is properly welded to the metal.
A knot wheel just chews it, melts it and spreads it around the surface even thinner making (even) harder to get off.
I tried a flap disc and sanding disc but both just clogged and ended up spreading the stuff over the surface again.
I tried 'shaving' it off with a stanley blade which kind of works if you want to take tiny amounts off....but would take weeks to remove all the coating off my items (a bull bar and a roof rack)
I also tried burning it off with a blow torch. It bubbles up but just melts back onto the surface. Scraping it while burning it removes some of the coating but makes a right royal mess and still leaves a lot to get off. It certainly doesn't burn off like normal paint would.
Paint stripper - doesn't even touch it.
I was hoping that I could pray to the powder coat removing pixies and next time I got to the unit all the coating had magically been removed, but alas, this was not much use either!
Please can anyone offer any advice to properly remove the stuff?
Many thanks,
Bruce.

Try a decorators stain and varnish remover and cabinet scrapers for more effect than a stanley blade. If that doesn't work find something highly acidic, powder coatings will react better to high pH than low pH. Hence why it tarnishes and peals from road use exhaust fumes are acidic

Thinners normally fetches it pretty well - esp if you can soak it in it?

Thanks for all the suggestions. Kev - good thinkning....I'll pop down to my friendly local powder coaters and see what they have to say. Adam, I forgot to add that to my list of epic fails.....A52 has got a large shotblast cabinet but the grit just bounces off the plastic surface giving it a flatter finish but doesn't begin to remove the plastic itself. The other problem is that a huge bull bar and an even larger roof rack (safari style rack) don't quite fit. I'll see what the local powder coaters say ;D

Man that's good powder coating, I've never really had a problem removing powder coat before its a bit more stubborn than normal paint but nitromors, elbow grease and a knot wheel has normally done the trick.
Can you burn it off with a blow torch?

Maybe some C4 will do the trick?? LOL

A guy i work with took his Disco' bull bar in to a local powder coaters to have them re-do it. They phoned him up & said they couldn't shift the original factory powder coat & his best bet was to find someone with a bonfire & sling the bull bar on it to burn it off!

Acetone?? or possibly Ketone[MEK] may shift it, both are highly volotile so work outside, Ketone is not generally available to the public as a solvent, but its the stuff used to glue plastic piping together

When I was trying to strip the powder coat of my wellers, I failed with the sand blasting too. It took the paint off which was over the poweder coat but not the powder coat itself.
In the end I took them to a specialist media blasters (most companies I spoke too said they wouldn't be able to get it off either) who uses what ammounts to a 747 jet engine blowing sand at about a million miles an hour!
He charged me £20 a rim which wasn't bad considering how much work is required to get the blood stuff off.

Used nitromors to good effect before. Get the gel stuff, spread it on, leave it for a bit and then get on it with the wire wool (or wire wheel in a drill if you're brave and well covered....).

Bruce, can't you give it a good scarring with the stanley - then the heavy gel stripper can get in behind and lift it? I take it - it'll be the fact it's the topcoat is impervious that is the main issue.....
Powder coaters remove old stuff first? Or just over the top again? Never knew......
they should be able to handle it if anyone can I suppose.....
Good luck

Any paint stripper with methylene chloride as the active ingredient will peel it right off. Here in the states it is sold as Jasco or "Aircraft remover"

aint read the whole thread so sorry if it's already been said
I'm sure i read the only chemical that has any real effect is found in Nitromors! I certainly have never had problem removing powder coat with Nitromors! Some heavy coatings too! Took a while on parts but got there in the end!
But remember, it eats alloy! (fast than powdercoat in some cases) lol
