  • thanks sausage. i will look it up. i have done a bit with 'wax resistance' - if you put anything waxy or oily on a bit of steel it stops the solder or braze taking. its a funny thing.... when you want to stick things then the tiniest impurity stops it from working. when you want to keep the flow away from a bit of detail you can be sure it will get in there and lock on harder than G St. Pierre. I will look at silicone though - it makes sense.
