Mini sandblaster for rust spots on keel?

[mogmog2]

I haven't tried (yet) but I've read enthusiastic comments about scrabblers; needle guns. Anyone tried?
Also Tercoo discs, not tried myself.

Sorry for the delay this is the sort of spot blast gun that I was on about.
You press then novel against the area that you want to blast but it only does small circles.

Seems like a variation on the ones I've been looking at.
I'm realising now that this idea is only going to work if I can easily hire a suitable compressor locally, or get very lucky on the secondhand market. I hadn't realised how much volume they required.

The one I linked to will work with a small 1.5hp 25 litre compressor of the smaller DIY type.
