    Our main rooflight has started weeping. The Germans use a non-setting mastic that is still soft.

    If I use sikaflex it's in for life, which may be OK.

    Anyone have the name of the non-setting type.

    Typical Herman the German rubbish that you have there Brian. .. Perhaps you should of got yourself a quality British van.

    God I've waited long and hard for this moment. ..

    But in answer to your question I would go with removing it and resealing with sikaflex 512.. I done both lights on my previous continental rubbish :)

    Brian....When I was in the Uk last year,... I called at a few motorhome / caravan dealers, I was wanting to buy 2 tubes of sikaflex to stick the new auto sat dish on the roof....I had no luck as the dealers said they do not use it now for the reason you have mentioned it is on for life...they could not remove it....but this is what I purchased which is what they said they are now using..."Hodgson" high performance Seamseal CV ...non drying beding sealant 380ml....from Belprin road, Beverley, near Hull HU17 0LN...www.hodgsonsealants.com.

    hear are a few links on EBAY.... http://www.ebay.co.uk/itm/Caravan-M...ervan_Caravan_Accessories&hash=item19ebad0daf

    Another company from Hull like the one I have just mentioned in my last reply thread....Hodgson Seamseal CV non drying bedding sealant..maybe because most of the caravans, motorhomes and static vans were or was made in the Hull beverly area:thumb: :thumb:

    Not from the Heki - but our van is the same age as Brian's so it's worth me checking.

    As I mentioned in previous threads we had to fix a problem in the rear locker (caused by something which had been modified by the time your van was made) and with the sealant cracking a little on some joints (fixed by resealing).

    The sealant problem is age related but it's something that could apply to all vans, irrespective of maker, because of flexing so well worth checking by any owner.

    sealant

    whatever you do do not use sikaflex if ever it goes wrong you wont be able to shift it. you need seamseal bedding sealant or carafax bedding sealant search for it on ebay. i am a caravan and motorhome engineer and would not dream of using an adhesive sealant on hekis.

    sorry but I dont agree. I have used sikaflex on my sat dish and my solar panel and have changed vans 3 times and removed each item without a problem of without leaving marks. I have also replaced a heiki light (although a smaller one than Brians without issue and two toilet sky lights the same way, having had to remove one several months later because I wanted more light. If you know what your doing, it can be removed. :Smile:

    Thanks everyone. In the end there was only one quick solution before Newbury, go to Spinney. There I bought a tube of Hodgesons. Sorted.

    The tricky bit was jacking up the Heki bit by bit with a bottle jack. The German goo was still tacky but as usual the Brits beat them.

    The seal seemed to be in two ways. The Heki had a runner gasket yet the Germans had bedded it down on some serious black mastic. Clearly both had failed a little bit.

    I cleaned the roof. Tidied up the rooflight and then ran a thick bead over the old rubber gasket. It's got to work, hasn't it !
