ESTI, guys, that CD2 works AWESOME!!
I used that last year before NOPI, and it stayed clean right until I swapped motors! Wowsers, that is GREAT stuff! Damnit! Now I let me "secret" out of the bag
WhiteLEgend, I can tell you what I do....
You need the following:
several old blankets
sheets (non satin

- wifey may kill you)
garbage bags
grocery size plastic bags
Areas of concern:
FUSEBOX
area in front of stock airbox (lots of electrical connections - cover with small sheet and a plastic bag)
area near ABS container (cover with plastic bags RH side of the car)
FUSEBOX
FUSEBOX
FUSEBOX
Did I mention, FUSEBOX?
COVER dipstick with a bag then alternator with a bag, THEN place the blanket(s) down in the area to cover them all...use your thickest one, the majority of the water can go down there)!
Any other miscellaneous areas with electrical harnesses...cover with the little baggies. Also, near the Master Cylinder are some harnesses, cover these. After that, just doublecheck your work and you should be good to go. FOLLOW the directions on the CD-2 verbatim....enjoy
