Two basic questions
 

1) When I wash my car, how bad is it to get a bunch of water into the vents on the side of the box? (Both soapy and non-soapy water)

2) What are the bumpers made of? I have some small scratches/cuts on my front bumper and I don't want a little patch of corrosion spreading. Unfortunatly, I can't tell if the bumper is plastic or metal underneath the paint. (What crud should I use to cover the scratch if needed?)

Thanks!

The driver side vent is the one you really have to be careful about spraying. I doubt you did anything to harm it (it does have a drain in there), but avoid direct spraying in that area -especially with a high pressure sprayer.

If your bumper cover is original, it's made of plastic (and if it's not, it could be fiberglass -either way, it's not metal). I would think you'd cover a scratch with some touch-up paint. It's my "crud" of choice.

Don't fret it unless you can see a puddle of water in the snorkel. There is an uphill climb,1ft. of tubing,an air filter,then another 2ft. of tubing before water would even get in the engine.

Think about it,Porsche designed the car to be a daily driver,I'm pretty sure the engineers thought about the possibility of water getting into the intake into account.
