Review: Does the job stops slight leaks - 2.8 TDI VW radiator slight leak. Replaced parts and bring still seeping coolant. I used the radweld and the leak stopped. Over a thousand miles driven and still no leak
Review: Fixed my leaking Toilet cistern - I was a bit desperate and couldn't afford new bathroom toilet. Tried other stuff but last resort was this. It's has fixed the leak and floorboards have dried out. The inconvenience of changing pipe work and decor would of cost 1ks.The porcelain cistern developed a crack due to Rusty bolts. Try this stuff before you go for the expensive option.regards Del
