    I have a loose bit of sealant on the roof of the Rapido in the joint between the front roof moulding and the main flat roof section.
    What sealant would the expert panel recommend. Some sort of sikaflex suggests itself but which one?

    Sikaflex 221 is more of an adhesive than a sealant. Also make sure whatever you use is in date.

    I would use Hodgesons flexible caravan sealant. Its a flexible non-drying sealant only, ie not an adhesive. Available from any good caravan accessory dealer.

    I Have used sikaflex 512 adhesive and sealant with very good results and would recommend it. If you had occasion to remove the cover strip on the ceiling inside as I did once, to reseal the aerial fitting, you would see that the joint has filled and sealed with a white rubbery material which is similar to or even may be Sikaflex 512. This is the same stuff you can see in the joint when you are outside on the roof.

    Although Sikaflex has been around a long time and is without doubt a good product, but there is these days a lot of cheaper competition... I have used the excellent Tec7 for some time which is basically an M7 polymer based Adhesive, it can be used as a sealer but not recommend where flexibility is required......for sealer situations you can use a Butyl flexible sealer or
    Geocel Silicone Rubber sealer which most yachting/boat yard's in this district use (y)
