So awhile ago i bought a three post spoiler from coomer and have been meaning to paint it and mount it on my car but...

I am kinda concerned about having to drill holes into my trunk and possibly having water leak in( i live in vancouver/portland, it rains ALOT here) the old "gaskets" on the post are long since destroyed

Is there another product i can use that would act smiliar to the rubber stuff that use to be one the bottom of the posts?

How do i know exactly where to mount it? I mean i can get it centered by splitting the difference of the trunk but how do i mark where to drill the holes?

OR We can step out of the box on this...

What if i cut off the threaded posts coming out of the spoiler and bondo or fiberglassed a peice of metal on the bottom of the post, then put strong magnets on the underside of the trunk to "grab" the bottom of the post and hold them in place?
Im talking like industrial magnets with at least a hundred pounds of pull on each one...

My only concern with that would be rattling it lose from my subs and scratching my trunk up alot...

Thoughts?

You can use a flat rubber washer that you can get from any good parts store that will fit around the posts and use a gasket sealant around it as well which will stop any water getting in. Use a slim nail with sharp point to mark the drill point easyest way to be honest but have someone hold it in place while marking save you have a load of marks on you boot. And the drill holes can always filled sanded and sprayed if you ever take it off. Don't know about the magnets never used industrial magnets

do you remember when you had a bike. Inside the tire you have the inner tube. I use that to make stuff like that. 10 bucks can get you a lot and you can cut it in sizes you want.

cheapo and nice.

im not looking for the cheapo way, but thank you for your input

Its just that i have learned the hard way that its usually a safer bet to spend the money on a well test product specifically desinged for that application. Im not trying to be a dick, but i got more than $2,000 sitting in my trunk and i dont want water leaking in and ruining my subs and amp...

bump

call the dealer, they may have the part number.

not many options but to go oem.


you can try black silicone, that is water tight if you know how to do it.

ok i just removed my seal on my 3 post spoiler and pretty much all it was was some really thick double sided tape with a rubber inside instead of foam. i would bet you could find the stuff at harbor frieght and cut to fit. right now i just put on a trd spoiler and im not even useing ne kind of seal right now and it hasnt leaked once once its tight the metal kinda conforms to the mounting hardware and creates its own seal im not sayinmg to leave it as it is but in my case im still working on my car and luckly havent had much rain. but i plan on doing the same thing with the double sided tape when the car is painted no use takeing a chance
