Hi, I had to strip the driver's door to fit a new window regulator, refit the inside door window seal, and "service" the door latch. This meant pulling off the original inner door water shedder, or membrane. I have a new one to refit, but I need to remove the black gloop that held on the original one.

I am interested to know if there is a quick and easy way to break down the gloop to get it off. Would white spirit work, or maybe rubbing alcohol ? I have to lift off the largest part of it with a chisel or a scraper, but I would like to get a clean panel before I fit the new membrane.

Any suggestions welcomed :)

I used a nylon trim tool to reasonable effect...putting a solvent anywhere near the gloop generally makes more of a mess...I wd just go with mechanical removal (and no chisel?!)

Is your new shedder oem? Or diy? I need to replace mine next time the door card is off

Thanks for the suggestions. Romanrob, I bought new water shedders, one for each front door as I have some stuff to do in the passenger side door as well as the drivers side door. They are around £45 each from Landrover. I just prefer to use original stuff where possible, if only to ensure a proper fit.

I had thought of making one up, out of plastic sheet, but there are some many lumps and bumps in the door itself that I decided not to bother.

The chisel bit was a bit of a desperate suggestion !!! I do actually have a set of nylon/plastic trim tools, one of which will do as a perfect scraper. The comment that you made about using a thinning agent had also occurred to me - that even with most of the butyl sealer removed I could end up with a gloopy mess. I will just have to try to remove as much as possible without resorting to thinners.

By the way, here are the part numbers, just in case you need them:
SHEDDER-FRONT DOOR WATER RIGHT HAND - EJD500600
SHEDDER-FRONT DOOR WATER LEFT HAND - EJD500610

I bought them in euros - €59.00 each.

Mad-as, there are an awful lot of lumpy bits when you look at the door after the original water shedder is removed. I think that to get the new membrane to stick on, without sticking up too much, I will have to remove as much of the old sealer as possible to try to prevent lumps under the new water shedder.

Interesting to see they are still available - good to know.

Do not put any chemicals to try to wipe or clean, you will make a mess the "goo" starts to liquify (?) or "melt" you will not want to clean that mess lol! Ask me how I know...
As suggested, scrape as much as you can and then put the new one on top... you can "squash" it fairly good upon mounting - just be careful to press on the door metal and not on some "hole" and therefore breaking the shedder.
I have taken them out and refit them a number of times, even with some taken from a breaker car, and never "cleaned" more that the old with a putty knife ... a little left does not affect the "new" one, the material does not break down on time.

Just don't scratch it with your fingernails ... also a bad idea :-)

You are probably beyond this point, but I make a nice cut of the shredder with a razor knife and then reseal it with Tuck Tape (might be a Canadian brand name).

I’ve recut in the same spot several times and resealed again with very good results. It seals well and you don’t see it once the door card is back on.

Thanks for the good suggestions. I think that I am agreed with not trying to use solvents to get the gloop [butyl] sealant off the door. I will probably end up with a big, dirty job.

I have noticed that the advice not to scrape the sealant off with your fingernail happens to be very well advised !!! It's pretty hard to get off later.

The scraper shown on amazon.uk looks like a useful item, but I do happen to have a couple of different glue spreaders [ex-Bostick back in the day] which should do the job.

Lastly, I am guessing that the Canadian Tuck Tape is probably the same as Duck Tape, in fact, I have a feeling that I have seen it over here in Europe.

It is not at all like Duct tape. It’s very thin very sticky tape that lasts way longer than duct tape, though it’s shear strength is very limited. It’s most often used here in building construction to seal vapour barriers, which is really exactly what I am using it for on the Rangie. It’s thin and virtually see through. People actually often use it to temporarily repair a broken red tail light lens. From a bit of a distance you don’t even know it’s there. The light shines right through it like the lens that broke.

I have never seen that type of tape before, I will ask some friends that are in construction.
The one Pierre mentions, you can find it easily in LIDL on offer sometimes, made by 3M comes on grey or black, very strong and resistant. It is quite "large" for something like a P38 door, but I cut it through its length and make it ... "slimmer"

Its available on Amazon UK - As far as I can tell it seems like they would ship to Eire as well?

Or cheaper option of same sort of product

I've used Duct tape to cover this sort of issue before - Duck tape I think is only a brand of slightly better quality duct tape in any case? Duct tape isn't ideal for the job, but works in a pinch. Alternative option depending on the original barrier (this works better with the plastic sheet type than the foam type) is to cut the sheet so that the original adhesive is left covered and then stick the new sheet directly on the old one. this sort of product works well for that https://www.ebay.co.uk/itm/275179415543
or this (same sort of product, better picture) https://www.ebay.co.uk/itm/314218336284
