Best way to remove powder coat?

I need to reweld an item that has been powder coated. Unfortunately it will be at least partly visible, so a neat appearance after the work is done would be good.

Any suggestions? Especially any that don't involve heavy expenditure of cash or time?

Plasticote paint looks very similar to powdercoat...

Second question - how big is the item in question? If it's only small you may find a local powdercoater who will slip it in with a bigger batch for a nominal charge...

We recently removed the powder coat on lower rear wishbones using a flap disc in the angry grinder. Worked a treat.

Flap abrasive disc to remove powdercoat, then fine wet and dry to feather down the remaining powdercoat edges. Recoat using a black enamel paint. Spray or brush, either goes on to a very smooth finish (probably a better finish than the exisiting powdercoat!)

Cheers

Nitromors paint stripper will disolve powder coating.

I used a wire brush in my angry grinder - not many coatings can withstand that sort of attack!

Powder coat is relatively removable with an angle grinder. A flap disc would leave a smooth finish but for welding I'd just use a grinding disc.

I'd second a vote for Plasticote satin black. Looks just like the Powder coat on my STM chassis and roll bar (though I can confirm that it's not!!!!)....

for me flap abrasive disc, and to paint, maybe epoxy paint from PPG will be nice

a blow lamp to soften it up followed by a wire brush will take it off.

If its a small item then I could powdercoat it for you for the cost of postage or you could used Hamerite's satin black which an exact match to the normal satin black powdercoat.
