Not sure if this is the right place for it as it's as much a review as a guide, but I got my hands on some Biostrip today. If this post is in the wrong place, feel free to move it. The full details and pictures are on my blog here

Biostrip 20 is available more or less everywhere online and I got this pot for a tenner. It's like slightly watery PVA and this single pot will do for an awful lot of minis as you will shortly see.
So, how do you use it? Well, you pretty much just dip the miniature in. For my first test I used the Orc Bloodbowl team and a lovely Saruman which I picked up at a car boot sale slathered in paint.
You dip the minis in and leave them to stand for an hour. Within a few minutes the pigment starts to slip off and after half an hour or so, the paint starts to crackle and lift. Give them a scrub and rinse and the miniatures are pretty much as good as new. Very little residue.
The metal Saruman proved to be an interesting test case: it turned out there were three layers of paint - the bottom one enamels. Three dips left it as bare metal with very little residue. So, the bottom line: this is exactly the product I've been waiting for. It makes stripping paint a minor job rather than a major chore, something you can set away while you're painting something else.
As you're simply dipping the miniatures in fairly thick liquid, this one pot would easily be enough to conveniently strip a normally painted warhammer/40k/saga/lion rampant sized force with a fair bit left over. And for a tenner, that's hard to beat.
