    Should I put sealant round base of spoiler??

    Just fitted(with help from this forum!) am Irmscher type spoiler to my Astra Mk 4. Could anyone advise if I should put sealant round the base of where the spoiler meets the boot lid? A couple of people have told me If I dont do this then the bolts will rust, which will eventually show through to the paint and make it look sh*t. I was thinking of using a clear silicon sealant same as used for bathrooms, but if anyone's can advise anything thats better I'd be grateful

    There should be a rubber/foam gasket that goes between the body and the spoiler.

    If you get hold of some stainless bolts rusting wont be an issue and make sure any holes made in the body are painted before you fit the spoiler.

    better still, you could grab some body panel adhesive that some manufacturers use to stick body parts. stick a splodge around the hole in the bootlid (obviously paint the drilled hole as techie says) then drop the spoiler on and secure the bolts.

    this way it will be well fastned and have the perfect water seal. can remember our old beamer's spoiler working free slightly on its bolt causing enough movement for the threads to rub against the bootlid, breaking the painted surface and allowing corrosion. it still had the foam gasket there though it wasnt doing its job due to the spoiler loosening its grip slightly. of course the down side to this is that the spoiler is now bonded making it hard to remove though if you have chosen a spoiler your happy with then alls good if a change is needed then its still not the end of the world just a bit elbow grease!
    Cheers Rich.

    Thanx People,

    I think I will do everything suggested above to be on the safe side.
    Spoiler is already fitted so I'll wait till the poxy english weather is better before taking it off and painting the holes, etc. Hopefully it wont have rusted by next weekend!
