Since I put the hardtop on for winter I am getting very bad condensation - so bad that there is ice on the INSIDE of the screen on frosty mornings - tightened everything up, can's see any sign of a broken seal or misaligned housing - any of you nice people have any ideas or similar experiences?

There must be some moisture inside the car for this to happen - so check to see if anything is wet - softtop box, behind the seats, footwells, boot (including the wells either side). If you have a leak, then you need to determine if it is the hardtop that is leaking or whether the water got in before the hardtop went on. If nothing appears to be wet, try closing all the vents when you park the car.

If you have no leaks, have you been using the AC?
This can sometimes cause issues.

Try popping a couple of Silca gel packs inside the car & see if it helps.

If its a buildup of condensation thats freezing over then try using a window cleaner/anti condensation solution. I clean my windows every now and then with that stuff and it really helps! You could be sitting in the car for maybe 2 or 3 times longer with the windows up and engine off before it starts to mist up.

This sideways motion is feeling all too familiar...

I read somewhere that a tray of cat litter on the floor absorbs moisture very effectively - just don't put the cat in with it. :lol:

Small Caravan De-humidifier works well.
Bought mine from a well known SuperMarket £2.99.
