Stripping powder coating

Folks,

I want to strip some very thick and robust 40+ year old powder coating from an alloy head.

I want to get it totally clean, right down in every nook and cranny.

25-30 years ago this was easy, just use Nitromorse. But powder coat just laughs at this shit today!

Can anyone recommend a pro outfit in the uk that can strip such a head to an ‘as cast’ finish?

Damn FE, I don't live in UK, but why don't you ask one of your local powder coaters? They should know.????
