Do you mean the "Brilliant" range?
Its the first time i have really used it and to be honest i was really impressed as i didn't expect much seeing as its very watery, although i think i used too much.
May give it a quick try on the exhaust of the cosworth tomorrow as a proper test for it, i will let you know the results as will take a few pics.
