What do people recommend?

I've stripped down and removed the housing went to seal it and realised the only plastic my sealant can't be used on is Polypropylene doh! I don't want to use silicone as it deteriorates over time and encourages rust. On the plus side everything was dry as a bone

You want the proper sealant cord from VW.  If you are lucky your local dealership might give you some.  If you don't have any joy i have some left still, send me a message and I can sort you some out for postage money.

Hopefully going to get some of the genuine sealant off Jimbof. But if it doesn't arrive in time what other mastick tube type sealants have people had success with?

I have to get the job done on Friday.

Thinks

Sorry, won't be able to get it to you for then.

 

A lot of people use silicon but I think it is a bad idea, the smell and the mess.

 

I've used Shell Tixophalte for doing door carrier panels - which is a flexible bituminous black sealant in a sealant gun cartridge, quite like the sealing cord but a lot "wetter" - apparently quite like roofing seal.  I think it would be a messy old job though...

I will check out the data sheet for it thanks. I don't like using silicone either as it should never be used on metal.

So after getting off the phone with a sealant specialist I was advised to use Otto primer 1227 on the housing and bond it to the car with Ottocoll m500. I will post how I get along tomorrow.

Cheers

All done! No way water is ever getting in. Highly recommend the sealer we used. we did it with minimal mess and put the car back together with no spare bits in half an hour. Next job upgrading the stereo and sorting out why the offside rear door isn't locking.

A few weeks ago I had the leaking door panel problem on a purchaced Ex taxi 07 Superb,  My neighbough saw me working on the car asked what was wrong, said he would be back  and arrived back with half a tube of black Stixall, told me to use that on the panels and they would never leak again...   He also knew about the pollen filter housing issue and helped me in Stixall "ing" that too...

 

As I had never heard of this stuff before I checked on Tinterweb afterwards and found this on Stixall

 

;STIXALL Extreme Power is the ultimate combined building adhesive and sealant, based on hybrid polymer technology, with the most Extreme power to both bond and seal virtually EVERYTHING to ANYTHING in virtually all conditions, even under water or in the rain! STIXALL Extreme Power offers almost limitless benefits as an adhesive and a sealant removing the previous application barriers associated with conventional products.

 

Oh  my carpets  now also stay dry when it rains ..

I now have another problem with water getting inside the doors. Sounds a bit like what you may have had.

Is this difficult to sort out?

Is there a comprehensive guide for doing the work?
