any good waterproof materials?

dudesky

Hello brothers sisters and friends
I currently having a water leaking problem in my trunk, due to poor spoiler installation. (damn me, stupid myself) As you know, it is pretty damn cold outside and because I bit rushed through the procedure, water leaks! I am planning to redo the installation tonight and if anyone had similar problem, any recommendation would be helpful! I am currently looking at to buy either "Rubber Foam Tape" or "Silicone washers" and put them inbetween the holes and where the machine screws contact with the spoiler brackets. I have no idea how that foam tape is waterproof? Wouldn't water gets soaked into the foam?? I used silicone sealant before but it still leaks. I guess the sealant didn't dry at all due to the cold temperature. What materials should I put inbetween the brackets and the trunk metal?

If it's closed cell foam it won't absorb water. I don't know if it will work as well as properly applied and cured silicone, but it's worth a shot. Marine grade silicone usually works pretty well. I'd give that another shot first.

I believe the rubber foam tape looks like this. Hopefully it is "Rubber Foam" and will do the job But I will also use silicone sealant on top of it for the better result

Be careful the added thickness of the tape doesn't cause more problems than it solves. If you have to tighten the screws down too much to account for its thickness, you may crack the paint or the spoiler itself.

I'd try gobbing some RTV on the bolts that pass through the body panel as a temporary measure to keep water out and then obtain the proper materials for installing the wing. Elastomer washers and a small bit of RTV on the washers/bolts/nuts should be all that is needed if the installation is done correctly.

RTV/silicone would not be my first choice for mounting the wing unless I were sure it would never have to come off again. It does need to cure at room temperature, if you can't find a warm place, wait until Spring.

Thanks for the suggestion I was kind of thinking that method. Somehow my silicone sealant cured at the temperature of below freezing point, but took like 2 days!

I would not use any silicone. I think wide close cell foam will do the trick. The thought of using plumbers putty around the screws also comes to mind. Plumbers putty is use around sinks, faucets, toilets and stuff. I would try the foam 1st though.

dudesky

wait a min, that's pretty smart idea too! once plumbers putty dries, is it still like rubber like or hard as cement?

kenchan

i would use caulk. but the surface needs to be dry to cure properly.

plumber's putty never dries. When it gets hot, it will liquefy. My plumber put way too much of it around the faucet in my kitchen and it leaked out for 2 years.

dudesky

woooo then I better not use plumber putty...because during the summer, it is going to get motherf*cking hot

Try Permatex Black Rubber Sealant. They sell it at most auto stores. The idea is to not trap water between the spoiler & the trunk & still have it watertight at the bolted connections.
