It's not as bad as these....

Oi, that's my arch brush you've got there!

OK, thanks for the advice everyone. I'll relegate the water blade to windows only.

Bit of a tip though - if you do have one, they're good for doing shower screens and mirrors etc in the bathroom - that's what I used my other one for out of my Costco 2 pack.

With regard to using drying towels with LT, I'd understood it was best to pat dry rather than move the towel around on the paintwork. I don't think I get how you can spread the LT without moving the towel back and forth on the paintwork.
