    Non setting mastic, tube or roll.
    Roll is VERY easy to use but dearer.
    Make sure surfaces are cleaned with meth or suitable solvent.

    If you mean sealing around the edges, then I was recommended to use 'The Works' from places like wickes by a local mobile caravan repairer. It's easy to use and non setting.

    I was up there yesterday just deciding how to get rid of the snooker table look (green baise) and thought I would re-seal round the edges of the roof lights and Sikoflex has been mentioned loads of time on Fun but when I looked there are two sorts advertised.

    A short time on google will get you the manufacturers specs, application instructions etc. You can then decide which if any is the product for you.

    By the way there are a few more than 2 types of sikaflex, and many equally good other manufacturers.

    We got the 221 sikaflex as it was the only one available in the french motorhome dealers here. Better have any we thought than none in case of leakages.
