I will start off by agreeing with Paul and Kev about radweld, that stuff is total sh1te.

I wouldn't put it in any car, not even my 20 quid metro.

The stuff we used was called Cargo metallic seal-up, and to be fair it did what it said on the tin, so to speak.

Its a lot more complicated to use than the just chuck it in and forget stuff, like radweld, but was worth the effort.

While looking on the net to find out a bit more about it, I came across a miliatry report on it, which I thought, added some weight to its credability, and demon tweeks flog it as well, and although there are expensive, there not a company I would consider flogging rubbish.
