The blowtorch method is admittedly tried an tested, but from what I've seen it's not perfect, there are always spots if it lingers a bit too long in some areas - although it might not show in pictures. The C4 actually chemically bonds with the bumper and puts it back the way it was when it was new. You have to rub it down with alcohol first and get rid of old product and it's probably not the easiest to apply, but when I say expensive I mean £20 so it's not like i went out and bought a blowtorch besides if it lasts two years thats pretty good and I might even get more than one application out of it. Anyway, I'll post the results since you're interested! I've booked the car in with my auto-electrician since I'm a bit of a ***** when it comes to wiring, also bought some yellow tinting film (not lamin-x just some cheap sh!t) for the fogs, so I should have them sorted in the next few weeks along wth the lighter. Any ideas what to do next? My heart is saying port, polish, cam but my head is saying G40. Although to be fair the missus is saying mortgage lol. I think I might band the rear wheels by 1 inch and sell the spacers...
