Cole,
That is an awsome shade of pink, my man ;-) Real eye-popper.
As to leaks, you have some good advice for the car washing scenario. another is to use water sparingly -- duh! Things will get more interesting when you get caught out in a storm. Look for any wires that may have been run from the front into the cabin and not sealed. My builder ran wire for the driving lights up in the wheel well, and drilled a 1/2 in. hole at the top for a 22 Ga wire, and just left it that way. Wet wheels are like a pump, and the hole was right at the pump exit. Mucho agua until I stuffed and tarred/undercoated that entry point. also, the hinge brackets for the bonnet can leak lots of air at speed, so on cold days you may notice that. Examine the seal between pan and body, esp'y at the front; use lots of undercoating. But here is the real deal, despite anything anyone else will say: these cars leak if driven in the rain. The question is how much, do you have a towel with you, and remember to lift the mats after any imersion, and let them dry.
Welcome to the madness.
