If you're on a budget, I'd recommend a big 'clean & strip' wheel, you know the type - sort of knotted fibres in resin. But get a polisher* (which you're going to need anyway for the paint) and get a 180mm diametre one. As long as you keep it away from edges which tear it up, it lasts for ages and will strip all the layers of paint to bare metal. Do the edges and corners with a knotted wheel, portable sandblaster or whatever.

It's not nearly as messy as stripper, but it is a bit noisy. And it takes a while, but not nearly as long as a knotted wire wheel. Plus it's cheap. I had no luck with stripper; I tried everything, including the cling film, but I think it depends on the type of paint and the type of stripper to get good results, and the chemicals used are majorly toxic and a pain in the date to clean up.

You could always do the bulk of it and get the last remnants soda or sand blasted. The corners aren't going to be susceptible to warping like the middle of a big panel so it's safe.

* When I say polisher, I mean the variable speed big angle grinder types from Supercheap.

bring out the gimp

that sounds like a great idea 2 or 3 guys with angle grinders with twistlock wire wheels. Also ensure you have 24 or so 120 grade wet and dry to rub down after the wire wheels.
I have done most of Sue's Morris Seams now and have just sprayed Kill rust matt balck and the orginal ones were done three yearts ago.

make sure everyone is wearing thier PPE

Let me know when and where

For a panel, the wire wheels work but head to bunnings and get a stripping disc for what ever size grinder you have... It works much easier and you dont end up having to dig all the metal wire out of your self, might still need the wire wheel in the corners but jeez give it a try they are much easier From bunnings I think they are blue and are in a plastic wrap, near all the grinder cutting discs and wire wheels... (and no I dont work at bunnings)
