What's the best way to do this? Seems it needs something a bit stronger than a wire brush in the grinder!

Background story: I had an inlet manifold powder coated. They didn't do the best job and bits of it have flaked off, then I dropped it and put loads of chips in it. So, I'm after getting it re-done, hence wanting to remove the old powder coat so a fresh layer can be applied.

Blow lamp and wire brush, but most powder coaters will put it back in the oven and burn it off

Ok... best to just take it to another powder coater then? I thought it might have to be blasted first.

Chris

the reason it flaked will be dirt under it so you will need to remove the lot before recoating or it will just flake off again
the blow torch and wire brush is the best way.
will they not fix it for free??????????

Nitromors worked for me

take it to the coaters, they will either blast it, or dip it 1.1.1 will clean it up

the coaters I use, and I wouldnt use anyone that didnt do the same anyway, will blast it, then coat it with a zinc rich primer, then colour coat it

I get stuff done with the RAL code or whatever its called, then its easy to colour batch with paint etc to body colour or perhaps touch it up in emergencies

Got all of the old powder coating off of my chassis with paint stripper,

What metal is it on?

I had powder coated bits grit blasted, then bead blasted. Those were aluminium. If its on steel you can just shot blast it to remove it.

Acetone works a treat....

It's an aluminium inlet manifold from an RS1800. I'd just buy another, but the HO type fetch decent money.

Might get the front and rear strut braces done too if it's that easy!

I'd forgotten about this thread, sorry! Just came back to remind myself of the best way to do this.

It's the latter. The HO type (from RS1800 and early Escort 1.8 Cabrio) is the best of the factory Zetec inlets as it has the biggest ports and largest internal diameter on the runners.
