Will the locking strip seal everything up or will i have to take it out and use sealant...

im not keen on sealant because i spent ages cleaning it all off, a mix 3-4 different types used in the past by previous people... no wonder it leaked!
[edit] seal is brand new one piece item (well they cheat and bind it, but built for a mini) and glass is spotlessly clean on sealing surfaces
To seal the windscreen effectively:
Place your seal in the car, with a couple of bits of masking tape to hold the top up.
Work your windscreen in using lots of glass cleaner, slippy stuff. Starting with the bottom edge and corners, then up the sides, and pull yer masking tape out, as ya come along the top.
While your winscreen is sitting in the seal without the filler strip, run your caulking gun of Selleys Dmastic around. Between the glass and the seal, and between the body and the seal. Best way to make sure you have enough is to pump it in till it squeezes out.
Do a rough wipe up of the excess sealant.
Fit your filler strip, again using plenty of slippy stuff. Make sure that you work it back into the corners to allow for shrinkage.
This will squeeze more goo out. With the handle of a screwdriver or something, run it along the seal, while pressing down to squeeze the little bit of extra Dmastic out. If ya dont it's gonna squeeze out anyway once ya start driving it.
Clean up all the excess Dmastic with kerosene, then go over it all with good quality glass cleaner.
Stand back, and check out yer nice shiny windscreen.
