Not quite the same as Radweld, Hunt around the local garages for a supply, it is also available on the net from a few places. I had an oil leak in a back differential caused by a seal that started as a weep and progressively got worse so my MOT man suggested Forte and it stopped the leak for another two years until I eventually changed the seals.
