Bought some of this at the weekend (£17 for 5 litres delivered) and had a quick dabble tonight. Great stuff, easy to use with unreal results. I know most of the people on here will wonder why I've shown the area around my strut brace but believe me, it was minging! Before anyone says anything about the crud going in to the water table, I did this in our yard where we have a discharge consent, pressure washers and gully sucker... Going to do a thorough job at the weekend!
