Shotblasting a Used Chassis...
Anyone done it?
How did you stop the grit from going into all the rivet holes?

I wouldn't do it in a word, too messy. Flap wheel in a grinder for me.

or those things that go in grinders that are like a soft spongy mesh, no idea what they're called but they're for stripping paint. I
stripped a calor gas gottle in a couple of minutes with one and the paint of those is really tough. I was seriously impressed at the speed it did it
and it's not at all aggressive on the metal, leaves a very smooth surface. I bought decent ones from a local welding supply shop.
The mental gymnastics a landlord will employ to justify immoral actions is clinically fascinating. Just because something is legal doesn't make
it moral.

What is it that you want to remove, is it rust or paint. If it's loose paint then wire brush, if it doesn't come off with a wire brush,
why not just leave it on and paint over it? I think you would have to be dead keen to remove every little bit of paint mechanically, after all, each
rail has got 4 sides and that's a lot of surface area, plus you won't be able to get all the paint out of the welds, unless they are super
smooth and concave.
I think the big question is how long has it got to last until the next rebuild? And where is it going to live in the meantime? If the paint
doesn't come off with a wire brush then leave it on. All the above IMHO, BTW
As some day it may happen that a victim must be found,
I've got a little list-- I've got a little list
Of society offenders who might well be underground,
And who never would be missed-- who never would be missed!

It's presently powdercoated, but is getting a bit tired.
I plan to paint it with epoxy-mastic... would the 'roughed' powdercoat provide a decent base for this paint?

I'm thinking that, as shot blasting doesn't sound like an option (rivet etc holes) and stripping the paint mechanically would be quite a
long job, involving fair bit of physical doings, that the answer to that question is sufficiently important to make it worth experimenting, even if
you had to mix up a whole tin of the stuff.
So that's what I would do, wire brush an area, removing the loose powder coat wherever it wants to come off, and de-grease it, paint over it
with the mastic, then leave it a week or whatever, and see how well it comes off when subjected to a bit of stress.

Seems like a sensible suggestion!
So this weeks priority is to get some sort of heater for the garage... waste of time doing it in the cold!
