i fitted my new rear light the other week and rear bumper so both lights came out i used some thick black gutter sealent on them and have pput them back in but am still getting a slight bit of water in when i washed my car , is this due to the fact that i didnt clean of all the old sealent do you think as it not the boot lid rubber as this has always been fine any tips out there cheers

This is what subaru and some other car manufacturers use.

more than likely yes.

I use this stuff: http://cgi.ebay.co.uk/ws/eBayISAPI.d...tchlink:top:en

Cheaper than butyl, easier to get hold of, can be removed easily, as can the lights if necessary, and is the preferred sealant for sealing and bedding, of caravan manufacturers.

If you are still getting water in, check the following, all of which have been known to let go:

in order of likelihood:

1. rear lights seal.
2. spoiler holes seal.
3. boot lid seal.
4. the little holes/flaps supposed to let air and water OUT, low down in each wing.
5. rear windscreen seal.
6. I've also seen lost drain plugs

What to do in each case:
1. remove lights, remove all traces of old sealant, refit withe new decent sealant, use plenty
2. Remove spoiler and any old dry sealant, refit with new decent sealant around each hole.
3. Remove boot lid rubber seal, re-apply with some sealant under it.
4. Clean out the area, dry thoroughly, make sure flaps can move and are DOWN.
5. This is a biggy: you need to get the car to a windscreen place, have them remove trim and check the seal. They will be able to see if it's gone.
If so, have them remove, reseal and refit the rear screen.
Luckily, the above is rare. It shows up as a wet rear parcel shelf and rear seat, rather than in the boot.

If you've changed the bootlid/spoiler, suspect either the fit of the bootlid, or the spoiler holes.

im sur eit the lights to be fair but will check all as the lights seem to have a touch of damp around the sealent like i say i need to get in the boot whiel some water is sprayed over it thats the best way i think

gutter sealant is no good mate its a non drying tar type thing,, get some good quality slicone , do not use tiger seal as you will never get them back out if needed,.

Fixed mine with RTV, no more water Clear the faces as best as possible and then be generous with application. Continuous bead helps

NO, no, no!

DO NOT use silicone type sealants. They make it a nightmare to remove lights again, plus they eventually split and/or crack.

Use this stuff: http://www.ebay.co.uk/itm/CARAVAN-SE...item43ab8f8f58

Made to bed in stuff to make it waterproof. Guaranteed not to dry out, split or crack.

And cheap with it.

If it's setting silicone, don't use it, you'll never get the lights off again when they leak.
You have been warned.

this is what is said on the tube

Silicone rubber sealants are one part moisture cure (R.T.V.). They are 100% silicone, which does not shrink and it will remain flexible after cure, suitable for use on most substrates

Used to replace pre-formed gaskets

Clear finish gives a virtually invisible joint

Resistant to high temperatures of up to 250 degrees

Resistant to water, transmission fluids and antifreeze

Will not crack or dry out

That's not my experience of RTV at all mate it's great stuff IMHO It's what most dealers/specialists use for exactly this I used it inside the boot rubber and refitted and it's spot on. I also use it on exhaust gaskets to great effect

No experience of the caravan stuff but as long as it's works
