Tried this yesterday on mine and a mates car an gotta say for the price were impressed,Products - Serious Performance

Bear in mind this works out about £10 cheaper per bottle(and its the same size-well its the same bottle )You use as little as you do with the blackfire as its the same kind of formulation-you`ll notice it goes on very simular though it isnt quite as thick/dense whatever so protections gonna be down a bit(remember its £10 cheaper) however visually is very little in it-in fact think this "could" be glossier,not gonna big it up much more as ive only applied 1 coat on mine -will repeat next wkend after washing an post results-love it so far though.

Dont think i`d call it a direct replacement (for the many fans of blackfire wet diamond all finish paint protection)-however its definately a lot less than £10 worse trust me theres not alot in it between em,ive also got about 1/4 bottle of blackfire left and i like it alot-however at this price will be buying this in future.
