Well the landcruiser has been in the panel shop getting a new rear bumper - bit of an adjustment of me driving a large car compared to my previous 2 wheeled honda. In my defence we both reversed into each other so 50 50 blame.

That means ive been using the escort to drive to and from work which is nice but after all the rain in the last week ive noted from leaking from the front windscreen, it seems to slightly pool in this corner and then start leaking through and running down the dash. What are my options? slap some sika in there and hope it seals up or get the windscreen removed and put back in?

Robbie you'll be surprised where the water gets in from, just cause it's pooling at the corner doesn't mean that's it's entry point.
Get to the auto shop of choice and buy windscreen sealer, do not ever use a drying silicon .
The leak will find the lowest point so it's best to seal the whole way around with a caulking gun lifting the rubber seal and applying plenty but not too much that it squeezes out everywhere messing up the car . The sealer will never set .

You might want to buy a cheap wifi back camera from ebuy or AliExpress, maybe even a beeper kit, great for those blind spots on the rig . Hope you get you cruiser back soon

The sealer doesn't set it just goes dry over 50yrs ! It's designed to stay pliable cause the screen and rubber actually move while your driving, next time you drive your escort reach out and rest your hand on the screen, seal, pillar and you'll understand why the sealer stays 'wet' . As said earlier, never silicone the seal in that's designed for gutters ! Anywho, your screen guy will fix it for you
