Hey guys, I used to have CF tails for my 5th gen and then recently put back my stock tails. When it rains, the trunk (where the spare is located) is filled with water :eek: . I was told that I can fix this by buying some spray foam, but where do I spray? Have you guys expericenced this? Any other suggestions would also help.

When you put the stock tails back in, did you take the rubber seal off the altezzas and put it back on the stock tails? Other than that, I don't see how water could be getting into your trunk unless the trunk wasn't closed properly or your trunk seals are bad :/

yea i had a leak but i actually tightened my spoiler, i guess my sub loosened it up or something cause i ran water over mine and i couldn't figure out where it was coming from but it wasn't the taillights, so my dad made the spoiler suggestion and it hasn't leaked since.

I got my keyhole and emblems shaved off the trunk about a year ago, and everytime it rains my trunk fills up with water too. i bet they messed up the seals. So the stuff is called "Great Stuff"? where could i buy it at.

90% of the time it's a leak from the taillight gaskets, so I don't know how you plan on using expanding foam to fix that . . . . I personally enjoy the option of changing bulbs without replacing the entire taillight assembly . . . . :)

Just remove the taillight assembly & adjust the gasket to make sure it's seating properly, that'll most likely fix it. If they're in bad shape, new ones are like $9 a piece.

If that doesn't work, other things to check are the rubber deck lid seal, side trunk vents, and moonroof drainage tubes.

moonroof drainage tubes that a good idea, i'd never thought of that. :bigthumb:

Most likely, it's the tail light gasket. Why not just buy new ones from Honda, they will seal better than anything from a can.

I see a small puddle of water in the spare tire area as well sometimes. maybe I should go check now.
Ummmmmm yea i would think so, don't make the mistake i did and forget about it and not look at it. i did that and let me tell you that water will mold over and smell like A$$, i had to shampoo my carpet in my trunk like 4 times and put he!!a Febreeze on it to get the nasty A$$ smell out.

If you guys have aftermarket bumpers, that why it is leaking. There is an air hole that is covered with the stock bumper, but when you aftermarket your rear this air hole becomes completely open, andy rain will get in from the spinning of your wheels, you need to cover it with some kind of stick paper or the aluminum that has the sticky edges on it. I think it is on the right side of your rear wheel after you pull away all the lining. There are more detailed threads about this for sure, just do a search. Peace

Yeah, if there's water collecting at the bottom of your trunk, you can be sure your rear seat cushion is pretty well soaked through (every time you hit the brakes water will slosh up into it).

Pull that thing out & let it air out - it took mine like 2 weeks to totally dry out, that's where the majority of your funkiness is going to emanate from.



Pretty friggin' nasty.

Actually, those vents (right & left side) are exposed to all the wheel spray with the stock bumpers as well. There's a rubber flap that normally keeps debris out, and it's possible some stuff could get in that way. Before I figured out my major leak was through the taillights, I covered mine up in that aluminum foil tape:



I'm not sure it helped much, I think my flap seals were still actually working properly.
