It hasn't soo much burnt my hands, but stripped the natural oils off, shame I don't use moisturiser really, as I am particulary prone to a sympton called "chapped hands". I believe, although I maybe wrong, its down to my natural hair colour (red/ginger) and skin colour (very pale), which also aparently leads to a lessor pain tollerence, I don't know if that is true. I just have to be careful when washing my hands, although I'm trying to find some hand soap that does have a moisturing efffect... normal soap should in theory have that effect as its usually a great big lump of fat.
At least the little Clio (which needs a wash! God, its getting filty thanks to the awlful weather that hinders my attempts to clean it every time) is still going, the Corsa is the next challenge, but that has a half a tank of petrol (with sugar and therefore a massive block, if the screen on the bottom of the clio's pump anything to go by, that means I should be safe everywhere else, e.g. fuel lines, fuel filter and injectors.) which disposing of it will be a massive problem as I have to drop the tank and filler hose full of petrol out, because there is simply no other way of doing it, the ring to the pump is rusted on, can't syphon out of the hose as thats blocked with sugar, can't pump it as its also blocked, so its drop and dispose of very carefully. I might seek some professional advice before I do it though, to see if there are other ways of removing the tank without the fuel in it (that probably means using a brass tool to make holes, which is pretty much what I think scrappies use).
Anyway, I'm way off subject and I should say, DO NOT TRY THIS AT HOME! Petrol is volitile enough and in the wrong hands, its a bomb! If you are concerned and don't know what you are doing (even if you think you do!) leave it to a garage, its much better, you don't want a Williams Garage like fire.
That sucks
