When I got my '05 there were water spots on almost everything
in the engine compartment so I cleaned it all and then I drove
during just one rain and now all the spots are back. How does
it get in?

Some thoughts: (Please try not to think me nuts)

I hate my engine compartment to get dirty.

So first I clean the engine. Depending on how dirty it was, I might use Gunk or just simple green.

Then I rinse everything very well and dry it.

Next this is the only done if the painted surfaces are very very dull I use towels and strips of cloth to act as masking to shield plastic and rubber surfaces and then spray a clear high temperature resistant spray designed for under hood use on these areas (Available at auto supply stores)

Then after that drys I use the glossy Armor All on the rest of the surfaces plastic and rubber.

Finally to reduce the clinging of water and it's spotting on surfaces I give a final overall spray of the Aerospace silicone 303 to everything.

Finally I try to not follow other cars too closely in the rain and try to avoid rain altogether.

With the engine area so prepared It stays cleaner and I can give an quick easy under hood clean up when I wash the car.

I do a very similar process under the wheel wells and the entire undercarriage..

You could really eat off any surface of my former Mod Mo.
