    If you want to use mastic from a tube take a bit of time and mask off around the rooflight where you dont want sealant to go with masking tape. You can then smug as hell run a finger along to make it look nice and neat and then peel the masking tape off to reveal a lovely edge like a professional had done it.

    No Mess really save from the yards of silicon covered tape so have a carrier bag handy to shove it all in.

    I would suggest you use a non-setting bedding mastic such as Carafax IDL 99

    this allows the seal to flex without leaking..

    use white spirit on a rag to clean off excess
