Just a quick update for 2011.
The technique and instructions remain the same as the guide on page one - only this time I have opted to show you tinfoil wrapped around the electricals. This is by far the better option over a freezer bag or whatever, because the tinfoil clings tightly to whatever it is you're wrapping it round
Spray APC over the dirty areas generously, agitate with a selection of brushes to help remove the dirt, and then rinse using a shallow angle and with the pressure washer as far away from the engine as possible.. allow to dry, and then apply a dressing of your choice - this one shows the 303 Aerospace Protectant:
Any questions, just ask. Not alot to dress on a GT engine, although the silicone hoses come up a treat using the 303, but I respect there's some newer Punto's and other cars on the forum who may benefit from this guide.
Cheers,
Matt.
